6 & 6.5 Creedmoor Load Data – What The Pros Use

This past year I asked the 173 of the top-ranked precision rifle shooters in the country about the load they were running in their match ammo. These were the guys that finished highest in the overall season for both the Precision Rifle Series and the National Rifle League (learn about the PRS and NRL). This was the first year I asked about the specific powder and charge weight they were loading. I made it completely optional, because I wasn’t sure if everyone was willing to share or would know that detail off the top of their head as they were taking the survey. I asked them to simply leave that question blank if they couldn’t remember the exact weight they were running. Of the 173 shooters that I surveyed, 162 of them said they handload their ammo and 82% of those guys were willing to share their load data with all of us! Thank you to all the shooters who completed the survey!

This article will cover what bullets, cases, primers, powders, and charge weights these elite marksmen shooting a 6mm Creedmoor or 6.5 Creedmoor found to work best in their rifles. What reloading components work best often depends on the particular cartridge you’re using, so I plan to cover the load data for each of the other popular precision rifle cartridges that at least 5 of these top-ranked shooters were using in these other articles:

  1. 6mm Dasher Load Data
  2. 6 & 6.5 Creedmoor Load Data (this article)
  3. 6BRX, 6BRA, and 6BR Load Data
  4. 6 & 6.5×47 Lapua Load Data
  5. 6XC Load Data

While I’d feel fortunate to know what load any of these top shooters are running, this set of data is the aggregate of well over 100 truly world-class shooters, so what a rich and unique data set to pull from insight from! Having such a large sample size allows us to draw more meaningful conclusions on what loads and components seem to work well across multiple rifle configurations. It can be tough to find good load data for a few of these cartridges, so I know this will help a lot of shooters. And while some of us enjoy tinkering with loads, knowing what load other accomplished shooters found as the “sweet spot” for a cartridge may help minimize time in the reloading room and maximize time at the range. I think even the guys who completed the survey will be interested to see what their fellow competitors found that worked best in their rifles.

Important: You should always reference a comprehensive reloading manual and start with the minimum recommended loads and work your way up. Many of these shooters could be running “hot” loads, and just because the load is safe in their rifles, doesn’t mean it will be in your’s. There are a ton of factors that vary from them to you, including exact chamber/barrel dimensions, brass specs, reloading scales, powder lots, seating depth and tension, etc., so it’s critical to follow safety precautions. Failure to follow safe loading practices could result in severe personal injury (including death) or gun damage to the user or bystanders. Technical data and information are based upon survey responses from other shooters under specific conditions and circumstances.

6mm Creedmoor Load Data

The 6mm Creedmoor (6CM) was the second most popular cartridge used by these top shooters, with 20% of the top-ranked shooters choosing to run it. It was only behind the 6mm Dasher in terms of popularity. The 6mm Creedmoor has 25% more case capacity than the 6mm Dasher and other cases based off the 6BR, which means you can typically run a little heavier bullets and/or a little faster muzzle velocities. Those things add up to better ballistics, meaning flatter trajectory and less wind drift. However, that extra horsepower usually comes at the cost of shorter accurate barrel life than the smaller cases, and you’ll likely have to manage slightly more recoil. In the precision rifle game, we’re all making trade-offs and trying to strike what we believe is the right balance of ballistic performance, recoil, consistency, and barrel life. Obviously lots of shooters feel like the 6mm Creedmoor was the right ticket!

6mm Creedmoor Bullets

Let’s take a look at the bullets top shooters were running in their 6 Creedmoor rifles:

On the chart above, the various colors represent where a shooter landed in terms of rank. For example, black indicates shooters who finished in the top 10 in the PRS, the darkest blue is people who finished 11-25 in the PRS, and the lighter the blue, the further out they finished in overall standings. The green colors represents the top shooters in the NRL, where the darkest green is the top 10, medium green is 11-25, and light green are the shooters who’s season rank landed from 26th to 50th. The chart legend itemizes the league and ranks each color represents, but basically the darker the color, the higher up the shooters placed.

One unique aspect about the 6 Creedmoor is the number of guys that were using match-grade factory ammo, and not handloading their ammo themselves. 6 of the 13 shooters who said they run the Hornady 108gr ELD Match bullet said they were shooting that from Hornady factory match ammo. And we aren’t talking about guys who finished low on the leaderboard either – one shooter using Hornady factory ammo finished 14th overall in the PRS Open Division! Just ten years ago it would have been unheard of to try to compete at this level of competition with factory ammo, but manufacturing has come a long way! One of the compelling aspects of the 6mm Creedmoor and 6.5 Creedmoor is you have the option for affordable, factory match-grade ammo. You can reload if you like, but there is always the option to just go buy a box of ammo off the shelf, which many shooters value.

If you excluded the guys who were running factory ammo, and only looked at what bullet the handloaders chose to run (since they could pick anything) then you’d only see 7 handloaders went with the Hornady 108gr ELDM compared to 12 that went with Tubb’s 115gr DTAC RBT bullet. There were also 7 shooters running the Berger 105gr Hybrid, so those 3 bullets combine to represent what 90% of the handloaders chose to run in their 6 Creedmoor rifles. I noticed those three bullets were very popular across most of the 6mm cartridges, so you’ll notice a theme over the next few articles.

There were also a top shooter in each league using the Nosler 105gr RDF bullet, which is fairly new bullet design. RDF stands for “Reduced Drag Factor” and Nosler claims their RDF bullets have the highest BC of any match-grade bullet on the market. (Learn more about the Nosler RDF)

6mm Creedmoor Powder

27 shooters said they handload the 6 Creedmoor, with 63% of those using H4350. There were a handful of other powders some of these shooters opted to use. Here is a breakdown of all the rifle powders these top marksmen were reloading in their 6 Creedmoors:

  • Hodgdon H4350 = 17 shooters (63%), breakdown of exact powder charge weights shown in chart below
  • Alliant Reloder 16 = 5 shooters (19%). Four of the shooters using 105gr or 108gr bullets said they ran powder charge weights from 40.0-42.2, with two shooters using 40.0-40.2gr. One shooter was using RL16 with the 115gr DTAC, and he was using a charge weight of 38.4gr.
  • Hodgdon H4831SC= 2 shooters (7%), with charge weights of 43.0gr with a 115gr DTAC, and 43.7gr with a 108gr ELDM
  • Alliant Reloder 26 = 2 shooters (7%), both using 115gr bullets with charge weights of 43.5 and 43.8gr
  • Hodgdon Varget = 1 shooter with a powder charge weight of 36.0gr with a 105gr Hybrid

Since over 60% of the shooters were running Hodgdon H4350, I want to show a more detailed distribution of powder charge weights those shooters said they were using on my survey. The color on the chart represents the bullet weight they were pairing that powder charge with.

While it appears that the 13 shooters that provided their exact powder charge weight of H4350 in a 6mm Creedmoor are spread out fairly significantly, 77% of those fall between 40.4 and 41.6 gr. That is just 1.2 grains of difference, so it seems like many guys found the “sweet spot” in that relatively narrow range. The guys running within that range (i.e. 40.4-41.6gr of H4350) with 26” barrels and 115gr bullets reported average muzzle velocities of 2950-3040 fps. The guys who were loading a 105gr or 108gr bullet over H4350 and firing them from 26” barrels reported muzzle velocities of 2980-3100 fps.

6mm Creedmoor Brass

Let’s take a look at what brand of 6mm Creedmoor brass these top shooters prefer:

Wow, that is a lot of different brands of 6 Creedmoor brass! Last year Lapua started offering factory brass for the 6mm Creedmoor, so I expected that to be the predominate choice of these top shooters – but clearly I was wrong! That’s why we like to actually look at the data, and not just say what we think! 😉 Hornady 6mm Creedmoor brass is clearly the most popular, 3 to 1 over the next most popular brands. Peterson Brass also made a surprise appearance with just as many represented as Lapua, including a shooter in the top 10 of both the PRS and NRL. Gunwerks brass also made an appearance in the top 10 in the PRS, so it is clearly capable. Alpha Munitions is a US-made premium brass manufacturer that some have said is as consistent as even the “European brands” (i.e. Lapua and Norma), and it looks like at least a couple of these top shooters would agree. Finally, Norma brass, Sig Sauer brass, and even Starline brass each had one shooter represented.

6 Creedmoor Primers

Now let’s look at the primers used for the 6mm Creedmoor. This is trickier than most other cartridges, because you can buy brass for the 6 Creedmoor that has a small primer pocket or a large primer pocket. Hornady’s original design was for a large primer pocket, but some believe small primers produce more consistent muzzle velocities and may take higher pressures and/or have a longer brass life because there is more metal in the case head and a smaller void/hole. Peterson Brass seems to provide some good insight into this:

“Casings with small rifle primer pockets do get more reloads than ones with large pockets. There is more metal around the pocket, so they hold up longer. There is an advantage to this for competition shooters. The first three or so times a casing is fired the more it forms to the shooter’s chamber, which results in more consistent muzzle velocities. So the more reloads you get after that break-in period the better. But we also make the 6mm Creedmoor in large rifle primer pockets. The larger primers seem to be less temperature sensitive – they perform more reliably in cold weather. So for someone wanting to use their gun to hunt deer the LRPs may be the better choice.”

I noticed on Graf.com’s product page for Peterson 6CM brass it has this note:

“If you plan to load above SAAMI max pressure and are concerned about primer-pocket leak, Peterson recommends you try the 6mm Creedmoor SRP [Small Rifle Primer]. While they do not suggest loading over SAAMI max pressures, Peterson’s small primer pocket 6mm Creedmoor have proven to hold up over SAAMI max pressures when tested in their universal receiver.”

I’ve actually heard of studies that proved small rifle primers were better, and others that proved large were better – so it continues to be a heated debate and it’d be a stretch to say there is a definitive answer to which is “better” at this point. Luckily with the 6mm Creedmoor, unlike other cartridges, you have the choice of small or large primer pockets, so everyone can pick a side they believe in. To the best of my knowledge, Hornady only offers 6CM brass with large primer pockets, Lapua only offers it with small primer pockets, and both Alpha Munitions and Peterson offer 6CM brass in either large or small, because apparently some shooters won’t buy one or the other. As long range shooters, we can have some pretty strong opinions, can’t we?! 😉

Finally, here is the list all of the primers the 6mm Creedmoor handloaders said they were using in their loads:

Because many of these shooters were running Hornady brass (which has a large primer pocket), we shouldn’t be surprised to see a lot of large rifle primers at the top of the list. The most popular choice was the Federal 210M Gold Medal Large Rifle Match Primer, with 55% of the shooters that were using large primers choosing it. There was also a top 10 shooter in both leagues, and a couple other shooters using Wolf Large Rifle Primers. Wolf primers are made in Russia, and according to BulletCentral.com, “In many cartridge types Wolf primers have shown excellent accuracy, and competitively low ES and SD. Wolf primers may require a little more force to be seated properly.” CCI BR-4 Small Rifle Bench Rest Primers was the most popular choice among the shooters opting for small rifle pockets.

6 Creedmoor – Exact Loads From The Top Pros

While the aggregate data of what guys are running is valuable, I wanted to also share the specific load data that a couple of the very best of the best were using in their match ammo. Scott Satterlee and Phillip Velayo are not only world-class shooters, but both are also very knowledgeable, long range rifle instructors. I’ve watched both of them help other shooters at matches. They’re some all-around good dudes, and I know I’d value their advice … so here are the loads those two are using in their 6mm Creedmoor rifles:

#5 in PRS & #8 in NRL: Scott Satterlee

Scott Satterlee
  • Cartridge: 6mm Creedmoor
  • Bullet: Nosler 105gr RDF
  • Powder: 40.2gr of Reloder 16
  • Case: Peterson
  • Primer: Wolf Large Rifle
  • Muzzle Velocity: 3075 fps from a 26” barrel (SD = 4 fps)

#10 in PRS & #9 in NRL: Phillip Velayo

Phillip Velayo
  • Cartridge: 6mm Creedmoor
  • Bullet: Superior Shooting Systems (Tubb) 115gr DTAC RBT
  • Powder: 38.7gr of H4350
  • Case: Gunwerks
  • Primer: Federal 210M Match Large Rifle
  • Muzzle Velocity: 2900 fps from a 26” barrel (SD = 7 fps)

6.5 Creedmoor Load Data

The 6.5 Creedmoor is one of the most popular cartridges out right now – and I’m a fan. I personally own a Surgeon bolt action rifle and a JP LRP-07 chambered in 6.5CM. I have lots of friends ask me for rifle advice, and I find myself recommending the 6.5 Creedmoor more than anything else. If I could only own one rifle, I would probably pick the 6.5 Creedmoor, because it would be a great choice for both competitions and hunting. Plus it has a relatively long barrel life, there are great factory rifles chambered in that cartridge, and you also have a ton of great factory, match-grade ammo options that are relatively affordable. In other words, it’s a hot cartridge for a lot of good reasons!

However, there were only 6 of these top shooters running a 6.5 Creedmoor. I bet some reading this may want an explanation for that – so I’ll do my best. Even though I’m a fan of the 6.5CM, own rifles in it, and recommend it often, I actually compete with a 6mm Creedmoor (view my match rifles). Don’t misunderstand, the 6.5CM is extremely capable. If you handed a 6.5 Creedmoor to one of these guys in the top 100, I bet they could still smoke me in a match (and a lot of other people). It’s more about the shooter than the cartridge! But, if you gave them a 6mm instead of a 6.5mm, they might be able to spot their own shots a little easier because of slightly less recoil, and that might help them correct a wind call that was a little off before it resulted in a miss at longer range. The ballistics for the 6CM are also slightly better than the 6.5CM (in most cases), but that comes at the cost of barrel life. There is no free lunch! So while I recommend 6.5CM to a lot of friends, if I had a friend who really wanted to optimize their rifle specifically for precision rifle matches, where terminal energy doesn’t really matter like it does in hunting or other applications, and they’re willing to replace the barrel more often for a slight advantage, then the 6mm Creedmoor or another 6mm cartridge might be the better choice. I believe that’s why 7 out of 8 of these top precision rifle competitors are shooting rifles in 6mm. There are still 23 of these top shooters running a 6.5mm cartridge (including one who finished in the top 10), so it’s clearly not a “dumb” choice – but at the absolute pinnacle of the sport, everyone is looking for the last little bit of advantage and most believe a 6mm provides that for these styles of competitions.

I know there are a ton of guys shooting 6.5 Creedmoor, so I wanted to provide as much help to them as I could, even though I only have data to share from 6 of these top-ranked shooters. Keep in mind that while these guys are experts, it is still a relatively small sample size. I will try to provide a little more commentary than normal to provide context where there could be bias due to the smaller sample size.

First, one of those shooters said they were running factory ammo. That shouldn’t be surprising since there are more great options for match-grade factory ammo in 6.5 Creedmoor than any other non-NATO cartridge. Hornady Match Ammo in 140gr ELDM or 147gr ELDM are both excellent choices, and I expected that was likely what that shooter was running – but they actually said they compete with Federal Premium Gold Medal Match with a Berger 130gr Hybrid. Honestly, I didn’t know Federal Premium was loading Berger bullets for the 6.5 Creedmoor. That’s awesome! Like I said, there are a lot of great options for match-grade ammo for the 6.5 Creedmoor. And one last note, that shooter using that Federal Premium factory ammo placed in the top 30 in the PRS Open Division, so it is truly match-grade ammo!

6.5 Creedmoor Bullets

Okay, now let’s dive into what bullets the guys shooting a 6.5 Creedmoor were using:

6.5 Creedmoor Bullets

It is probably no surprise to see half of the shooters were using the Hornady 140gr ELD Match bullet in their 6.5 Creedmoor rifles. That bullet is a great pair for the 6.5 Creedmoor in terms of the velocities you’re able to get and the BC of the bullet. You can also see there was one shooter running the Hornady 147gr ELDM, Nosler 140gr RDF, and Berger 130gr Hybrid.

There is one bullet that is suspiciously missing from this group: the Berger 140gr Hybrid. That is another great option that would likely be well represented if we had a little larger sample size. In an upcoming article I will show what bullets the shooters running a 6.5×47 Lapua chose to load, and 65% of them picked the Berger 140gr Hybrid, so it’s clearly a great bullet option in 6.5mm that simply seems to not be represented among these 6 shooters. The chart below shows the most popular 6.5mm bullets used by these top-ranked shooters overall, and not just the ones guys were running in their 6.5 Creedmoors. You can see the Berger 140gr Hybrid is worth considering, along with several other outstanding match-grade bullets.

Best 6.5mm Bullets

6.5 Creedmoor Powder

5 of these top shooters said they reload for the 6.5 Creedmoor, but the data on what type of powder they use was more spread out than some of the other cartridges. There is really no way to show patterns in the data, because of that. However, in order to provide the most complete data I can for all my 6.5 Creedmoor shooter friends, even with a relatively small sample size, I’ll simply provide the individual loads these shooters said they were using on the survey:

RankBulletPowderPrimerCaseBarrel LengthMuzzle VelocitySD

Please remember that these guys may be running “hot” loads, and just because it’s safe in their rifles doesn’t mean it will be safe in your’s. Read my highlighted tip in the intro of this article, and consult a comprehensive reloading manual for safe loading practices.

6.5 Creedmoor Brass

Of the 5 top-ranked shooters reloading for a 6.5 Creedmoor, they were all using a different brand of brass! I’m getting the sense that these 5 shooters may be type of guys who like to buck the trend, and go their own way! 😉 I can certainly appreciate that! When it comes to brass, there was 1 shooter using each of these brands:

  • Alpha Munitions
  • Gunwerks
  • Norma
  • Peterson
  • Prime Ammo

It was surprising to see them all spread out, but what more surprising was that none of them were using Hornady or Lapua brass! While all the brands I listed above produce high-quality cases, this seems like another area where the small sample size could be skewing the results. We saw that 44% of the shooters using a 6mm Creedmoor chose to run Hornady brass, so it seems extremely likely that if we had a larger sample size you’d see Hornady as one of the more popular brands of brass for the 6.5 Creedmoor.

Also over all the 150+ shooters who were surveyed and said they reload their match ammo, 72% of were running Lapua brass. Lapua has been making 6.5 Creedmoor brass for a couple years, so it’s shocking that there aren’t more of these guys using it. I don’t want to insert my own bias here, but once again it seems extremely likely that if we had a larger sample size you’d see a significant number running Lapua brass, more similar to what we saw with the 6mm Creedmoor.

For context, the chart below shows the most popular brands of brass across all of the shooters, regardless of what cartridge they were using. None of the brass manufacturers offer cases for every cartridge these guys were using, but most of them do offer brass for the very popular 6.5 Creedmoor. I hope this helps fill in parts of the bigger picture that perhaps this small sample size could be missing.

Best Rifle Brass

6.5 Creedmoor Primers

Similar to the brands of brass, the 5 shooters that reload their match ammo were using 5 different kinds of primers. I’m sensing a pattern here! There was one shooter using each of the following primers:

Like we saw for the 6mm Creedmoor, it is a mix of both small and large rifle primers, because different brass manufacturers offer 6.5 Creedmoor brass with either large primer pockets or small primer pockets … and a few brands offer both. While all of the primers these guys are using are clearly excellent options, since you are able to pick from any small or large rifle primer with the 6.5 Creedmoor, I thought it’d be helpful to include the overall popularity of different brands and models of primers these top-ranked shooters were using in their match ammo across all of the cartridges.

Best Rifle Primer

CCI and Federal absolutely dominate in terms of primer popularity. Just scan down the left side of that chart and notice how many times you see either “CCI” or “Federal.” Isn’t it interesting to see the complete absence of primers from companies like Winchester? There was also only one shooter in this entire crowd using a Remington primer. That doesn’t mean they aren’t capable or high quality, it is just interesting to see they aren’t represented among this group.

The clear favorite overall is the CCI #450 Small Rifle Magnum Primer … by a huge margin. As I mentioned in a previous post, the CCI #450 is a magnum primer, but from what I heard it produces some extremely low standard deviations (SD) in muzzle velocity, meaning the ammo is extremely consistent shot-to-shot. I’ve also heard that magnum primer doesn’t show signs of pressure as quickly as some of the other softer primers, so guys might be able to run slightly higher pressures with it. I can’t say for sure why so many of these shooters prefer it, but the data clearly shows they do.

  1. I know this is off topic, but did you ever have any luck with the 300 norma mag? I have been working with that caliber for awhile now and it is really finicky for me. Have you ever gotten the Sd numbers down to the same as your 338 lapua? thank you

    • Jason, I didn’t ever get the SD’s on my 300 Norma Mag down as low as my 338 Lapua. That 338 Lapua load has ridiculously low SD’s, so I’m not even sure that’s possible. With my 300 Norma, I typically get 7-11 fps SD’s over 10+ shot strings. Lower would be better, but honestly that is good enough for what I use that rifle for. Honestly, I’ve never heard anyone brag about the low SD’s they get with the 300 Norma Mag. I don’t think it’s as easy to get consistent loads with as some other cartridges out there. The external ballistics are awesome, but the internal ballistics of that cartridge might not be as good as some others.

      Thanks,
      Cal

  2. Wow I was expecting to see guys running much faster than me. Those 6.5 CM’s are running much slower than I am. Normally I’m at 2880, but this new barrel sped up to 2917 (validated today). Hornady brass, 140 ELD-M, H4350 with my go-to load for four years.

    Thank you so much for taking the time to gather and present this information, it gives us a “peek under the hood” at the top of the sport, and evaluate options if we’re interested in making a change.

  3. Having a few boxes of 6mm Hornady 108gr ELD-M bullets to develop with, the first thing I tried was to examine and weigh the factory charge of the 108gr Factory Match ammo. The weight came in at 39.8gr, and the best match to what I had to use, among a dozen or so extruded powders, was Reloader 17. I set the CBTO back 0.010 from my measurement of my (Ruger Am Predator) chamber. I was surprised to hit a good load so fast by besting the factory Match ammo by an almost 50% smaller group @ 100yds of 0.6 MOA. I used once fired, full length resized Hornady brass and Federal GM210M primers. Rifle is stock, but in a Oryx chassis.

    Will certainly move to H4350 next as it is a stock powder. Also trying to find RL-26, but it’s out of stock most everywhere.

    • Thanks for sharing your experience, Russ. It can be tough (or possibly dangerous) to try to reverse engineer a load without knowing exactly what powder they are using, so I’d definitely advise caution there. But it sounds like you’re happy with the results.

      I know a very accomplished gunsmith who has a theory that bullet jump actually has a larger impact on group size than even powder charge weight. He’s done a lot of tests over a lot of the rifles he’s built, and seems pretty convinced. I do think there is something to that. My approach to load development is to start just off the lands (like you did, with about 0.010″ of bullet jump), and try to figure out what powder charge weight produces the lowest standard deviation in muzzle velocity. I really don’t pay much attention to group size at that point. Once I figure out a powder charge weight that produces low SD’s (wanting something in the single digits), I start playing around with the seating depth and look at what that does to group size. I know everyone has their own little approach to this, and mine changes over time … but that seems to do me well.

      I do think that just by customizing the bullet jump to be minimal in your rifle, you’ll always see an improvement in group size over factory ammunition that has to have some generic amount of bullet jump (usually a substantial amount). Sounds like that is your experience too.

      And yes, powders are once again being hard to come by. It’s a seasonal thing that comes in cycles. I’ve heard rumor that some military contract has caused Retumbo, H1000, and RL-26 to be close to impossible to get. That was 2nd or 3rd hand rumors, so I don’t say that with much confidence … but those powders do seem to have completely vanished.

      If someone reading this knows where to get a couple 8 lb kegs of H1000, H4350, or RL-26, please let me know!

      Thanks,
      Cal

      • Thanks for the reply Cal. You are of course spot on regarding the danger of doing what I did. My reason for proceeding was that everything I could check about the load was correct, and the load data for the ELD-M for RL-17 was well in range, so I could have just selected this load at random. Hornady had just released load data for 6mm CM.

        Regarding the powder, I did run across 8 lb bottles of RL-26 for $225, but did want to spend that much on a powder I have not tried. Where I am, 8 lb jugs of H4350 are not hard to come by.

      • Awesome! Yeah, nothing is worse than buying an 8 lbs keg of a powder you’ve never used … and then it’s not the powder you end up going with.

        In related news, anyone looking for 8 lb keg of Reloader 50 or VihtaVuori 24N41?! 😉

        Thanks,
        Cal

      • H4350 at Midsouth

    • Factory powders are not always the same as the powders sold to reloaders , as factory has blends made and one of the factors very important to them but not to average reloader in metering in their povder charging machines.
      So weighing factory loads is often pointless.

  4. What’s your thoughts on using IMR 8208 XBR for 6.5 CM loads?

    • Doyle, I can’t say that I’ve tried that powder, so I just don’t know how it’d do. I will say that a lot of these guys like running the Hodgdon Extreme Series powders because they have a coating on them that reduces how sensitive they are to fluctuations in ambient temperature. That just means if the match starts at 70 degrees and gets up to 104 by mid-day, your muzzle velocity won’t be drastically different than when you started. … and yes, that was a real-life example of what happened at the last PRS club match I shot in Midland, Texas! Wow, it was hot!

      I know there are a couple other powders that are supposed to have similar coatings, but I’m not familiar enough with all of them to say if that’s one of them. I looked at the data and it doesn’t look like any of these guys are using IMR 8208 XBR. Two of them used IMR 4451, but that was the only IMR powder used. For comparison, 143 of them used a Hodgdon Extreme Powder like H4350, Varget, H4831SC, or H4895. If it were me, I’d start by trying one of those if you can find any in stock.

      Sorry, I couldn’t be more help!

      Thanks,
      Cal

      • Thanks for the reply. Hodgdon is located in Shawnee, KS, which is about 10 miles or so from where I live. The latest Hornady manual shows that powder, guess I should have bought one yesterday instead of today.

  5. Interesting as in very interesting! I run a 6 SLR so the 6 CM is of interest to me. I was determined not to run H4350 so I would have good powder availability. I eventually gave up and I run you guessed it… 4350.. why? it’s more consistent at any load!
    My goal in running the bigger capacity was to run H1000 or H4831sc and extend barrel life not looking for highest velocity both ran good 7-10 SD in the .7s at 100 yd H4350 5-8 SD .3s at 100 running 40.0 gr 2965 fps I’m also running Winchester mag primers so odd one out there. But I’ve had problems with CCI not firing in -20s and I shoot alot in the winter. (Its called Canada and I love it) both are consistent SD for me.
    I have a process that I go through when developing a load it’s the same every time my goal is get it done and go shoot. The focus is consistent loads over say accurate but normally both are the same load. I run DTAC RB115 if I can find them or Berger 115 VLD Hunting. Both shoot the best at 40.0gr and the same seating depth. I dont need to set anything different to switch bullets. I jump both .100 to .120 I dont find either to be fussy for seating depth and they are more consistent jumping further. Life is interesting to say the least. I really enjoy your work of love here “Looking at the data” and regularly keep looking for new articles! Best Regards and shoot safe.

    • Thanks, John. I actually run H1000 in my 6mm Creedmoor with the 115gr DTAC’s. However, it seems like H1000 is harder to find now than even H4350, so I’ll probably be switching to conserve my H1000 for my bigger cartridges.

      And I’m with you on putting priority on consistent loads (in terms of muzzle velocity SD) over the load that produces the smallest groups. What I’ve found is if a load produces a small SD, it will almost always group well, but just because you fire a couple small 5-shot groups with a load doesn’t mean that it will have a low SD. If you’re shooting out to 1000 yards, if you don’t have a low SD you will get a lot of vertical stringing and your group size at distance will be worse than it was at 100 yards. Many of these veteran shooters thing the same way. Consistent muzzle velocity is critical, even though we all love to fire that super-tiny group!

      Thanks again for the kind words. Glad you’re enjoying my data-driven style!

      Thanks,
      Cal

  6. Very nice

  7. Hi Cal, Great article as usual, with lots of real world data. I have just had a 6.5CM barrel made for my AXMC, so this article was well timed for me! In the UK, the ELR scene isn’t as well developed as the US, & although everyone has access to the internet, on the ground & face to face info & help is not so easily come by.
    So, thank you, & I look forward to putting this & Bryan Litz’s data to changing my $ into accurate & precise groups.

    • Thanks, Sven. I thought this post would help a lot of people out there who might be in your same position. It takes a lot of time to put all this stuff together, so I really appreciate you letting me know that it helps.

      Thanks,
      Cal

  8. Surprised the 107 smk wasn’t used. IMO it’s better than all but the berger. Although I guess the dtac is made by Sierra?

    • Good question, Zach. I think there was a couple shooters using that in other cartridges, but just not the 6mm Creedmoor for whatever reason. And yes, the DTAC is made by Sierra … but sold by David Tubb.

      Thanks,
      Cal

  9. Interesting and thought provoking info….thank you for gathering all this. Slightly off topic…any plans to do the same research with the 223 and 308 for those that do shoot those calibers as trainer rifles? I have a Tikka T3X Varmint in a XLR Element chassis and I’m a fan of the 223 for what it is….inexpensive, low recoil, ubiquitous and versatile for it’s intended usage.

    • Hey, Don. I haven’t ever asked them anything about if they use a trainer rifle and if so what cartridge. I like that idea though, and added it to my running list of things to consider asking these guys next time. Thanks for the suggestion.

      I did train one day before a match with a guy that was the PRS champion a few years back and he brought his 223 training rifle, which was built on a Surgeon action and in the same stock he used in competition with the same optic. He brought it along with an ammo box of military surplus ammo and we used it to practice positional stuff. It was pretty ideal. As long as there is enough recoil to throw off your sight picture, then it’s realistic enough to use for training (in my opinion). If it’s the same stock/optic setup that’s ideal. But, I’m sure you know all that. I do like the idea of asking about it though. Thanks for suggesting it!

      Thanks,
      Cal

      • You’re welcome Cal.
        It’s interesting that the champion was just using surplus ammo to practice but I can see the point…it’s low cost and stress while still getting the mind/body training and connection in.
        I’m sure there’s a wealth of info for 223 load data in other shooting disciplines such as FTR but not sure how often you attend those events. It might be such that you gather that data over a longer period of time through casual interactions and conversations with friends, family and other shooters that has attained a high level of precision with the caliber. Just throwing it out there, of course. I have a feeling it could be a popular blog given the popularity of the cartridge.
        Thanks again and have a good one Cal!

      • Yeah, and it was just for practicing positional shooting, where you are shooting off a barricade or from some other improvised position. When we practiced prone shots on small targets at long distance we used our competition rifles. But it worked well for positional stuff where your wobble is usually 3-4 times bigger than your group size anyway.

        I doubt many of these guys put a lot of thought into their load for practice ammo. I know I certainly don’t. I do think you’d have to tap into other shooting disciplines to get data on great 223 loads across a wide range of expert shooters. If you (or anyone else) has a connection to the ruling body of those kinds of organizations, I’d consider working with them to survey the top shooters in those sports. It would be interesting to see.

        Thanks,
        Cal

  10. Its interesting to see comparison in 6Dasher and 6Creedmoor loads and unless people start using heavyer 115 bullets there is litle reason for 6 creedmoor to gain any ground. Not enough gain for 25% more powder . Also by now feeding Dashers is kinda resolved

    Heavy for caliber bullets is what sunk the 6.5×47 that was originaly designed to shoot 108 and 123 bullets and now is to small of a case for 140-147 ,people end up pushing loads to very hig pressures to make some MV and even then its not even close to 2900fps we kinda like to have. Even 6.5Creedmoor is hardpressed to push past that.

    147bullet sure looks like it would be one mean pil in 6.5-284Norma a caliber that used to be king of the hill in Long range shooting years ago before straight .284 took its place.

    Similar 6BR and 6Dasher are small cases for use of heavy 115 bullet ,that is why Tubb made 6XC (6Creedmoor looks like its sibling)

    • Mr.T, as always … great points all around. I really can’t argue with any of your points.

      Over the years, I’ve become convinced that bullet design really drives cartridge popularity, and not vice-versa. If a new 120gr 6mm bullet is introduced that is really amazing and provides a clear advantage, then we’ll see cartridges optimized at launching it become really popular. Likewise, if a new 95gr 6mm bullet is released that has close to the same BC as the 105gr, then I wouldn’t be surprised if we don’t see guys start to slide down to even smaller cartridges. That’s basically what happened with the explosion in popularity of the 300 Norma Mag. Really what made it popular was the design of the 215gr and 230gr Berger bullets. Before that, there was a gap in bullet offerings. There wasn’t a high-BC, heavy-for-caliber option like there was for 7mm or 338 calibers, and when those bullet came out … viola, the scene was set for a new 30 caliber magnum to become very popular.

      And I’ll just try to safely avoid the comment about the 6XC and 6mm Creedmoor being siblings. LOL! They are obviously very similar in a number of ways.

      The feeding issues with the Dashers is a problem, although like you said … enough guys have seemed to overcome it that maybe we can move it to “non-issue” status at this point. The Dasher is very consistent, and I think as we’ve matured in our understanding of what matters at long range … we’ve learned consistency is at least as valuable, if not more valuable than raw horsepower. I also think some of that has to do with the improvement in our predictive ballistics, and having tools that adapt the solution for the current atmospherics, more sophisticated solvers, and shooters that are better educated in how to use them effectively. Think about it, if you don’t know how to run a ballistic solver, then you need a really flat-shooting rifle. If you have a good rangefinder and are good at running a ballistic solver … having a flat-shooting cartridge just doesn’t matter as much anymore.

      Anyway … I could philosophize all day! I do enjoy and appreciate you sharing your opinion. Great points!

      Thanks,
      Cal

  11. I’ve been reloading a variety of bullets for my
    6mm Creed. to see how they perform at the Range
    103gr – ELD-M , 105gr – HPBT- RDF , 107gr. – HPBT MK
    and 108gr. – ELD-M
    All of them are great bullets for the 6mm Creed.

    • Thanks for sharing. I use the 103gr ELDX for hunting and even run reduced recoil loads with that for my girls, and it works great.

      Lots of great options for bullets in 6mm, maybe more than any other caliber.

      Thanks,
      Cal
