The quality and consistency of brass cases are crucial for achieving precision in reloaded ammunition. Variations in case dimensions, wall thickness, and internal volume can significantly impact chamber pressure and bullet velocity, leading to inconsistencies in accuracy. If you don’t start with high-quality brass, you’ll never add enough steps into your reloading process to turn it into uniform, match-grade brass.
Fred Sinclair was a competitive rifle shooter and gunsmith who founded Sinclair International in the 1970s (later acquired by Brownells). Fred began by crafting high-quality reloading tools for Benchrest shooters and varmint hunters – a group known for pushing the boundaries of precision rifles at the time. Fred had 50+ years of experience reloading, and in the Precision Shooting Reloading Guide, Fred Sinclair explained, “The first step in case preparation is to obtain quality cases.” Sinclair says the goal of brass prep is for “our cases to be nearly identical prior to firing a shot.” So, the more consistent brass you can start off with, the better.
This article shares what type of rifle brass the 200 top-ranked shooters in the Precision Rifle Series (PRS) choose to run in long-range rifle matches. (Learn about the Precision Rifle Series.) This data is a large sample size of competitors that are also the very best precision rifle shooters in the world. If a large group of these guys are using a brand to get to the top of the leaderboard at pro-level, two-day PRS matches across the country – you can know for certain that it is very consistent and capable of world-class precision.
I’ll mention that this is the first article that is based on the most recent survey of the top-ranked shooters in the PRS at the end of the 2024 season. That survey was just after the PRS season finale match earlier this month.
Best Rifle Brass
Let’s dive right in! I’ll provide a more detailed breakdown of what brand guys are using for specific cartridges later in this article, but let’s start with this chart showing the most popular brands of brass among these elite marksmen regardless of what cartridge they were running:
Many people are likely surprised only to see 4 brands of brass represented among all 200 of these shooters! I was surprised by that myself. The last time I published data on the brass these guys were using was back in 2019, and there were 10 brands of brass represented then, including Alpha, Gunwerks, Hornady, Lapua, Norma, Nosler, Peterson, Prime, Sig Sauer, and Starline. So, there has been a lot of consolidation among this group into just a few of the premium brass manufacturers over the past 5 years.
Alpha Brass: 67% of Pros
Alpha Munitions was by far the favorite rifle brass among pro shooters, with 67% choosing to run Alpha brass. That included 6 shooters in the top 10. It basically was the majority of shooters, regardless of how you slice it. In the survey I conducted at the end of the 2018 season, only 5% of the top 200 shooters said they used Alpha brass. What a massive swing over just a few seasons!
Alpha Munitions was founded in 2015, and here is how they defined their goal:
Alpha’s Goal: “To manufacture the highest quality most consistent rifle brass on the planet, something we call Alpha Grade. Alpha Grade means we exercise exacting control over every element of production, while utilizing the most advanced technologies in both manufacturing and quality control. We don’t manufacture different grades of brass. If it’s not Alpha Grade it doesn’t go out the door.” – Alpha Munitions
Their primary audience is the precision shooters who weigh to the kernel and measure to the thousandths. Frankly, it’s the shooters that are represented in this survey – and the ones reading this article! 😉
I met with some of the founders of Alpha at SHOT Show 2016 and heard about their vision for the company. For the longest time, Lapua was the de facto gold standard when it came to high-quality brass. Other European manufacturers were likely the next tier of brass quality, while most US-based brass manufacturers were trailing in terms of quality. Much of that had to do with the fact that US-based manufacturers weren’t using modern manufacturing equipment. Alpha’s founders came with a wide range of experience in other industries, including medical devices, pharmaceuticals, and engineering, and they understood the potential of bringing modern, state-of-the-art equipment and rigorous quality control processes to the brass industry. That includes an industry-leading inspection system that has multiple points of inspection on every single case.
Alpha Munitions says their OCD (Optimized Case Design) Technology is the first major advancement in brass manufacturing in decades. In testing, OCD brass plastically deforms less than competitors at identical loads, resulting in better consistency, brass life, and performance in all environmental conditions. That’s why they claim that OCD brass is the strongest, most durable rifle brass ever produced, giving shooters the widest performance envelope.
Here is a video where Tom Danielson, Founding Partner/Owner of Alpha Munitions, explains what makes Alpha brass different:
Alpha makes factory cases for most of the cartridges this group of shooters uses, far more than any other manufacturer. For example, they make factory 6mm Dasher brass, but Lapua does not. If you wanted to shoot Lapua brass out of a 6 Dasher, you would have to buy Lapua 6mm BR Norma brass and then fireform it in a Dasher. But if you choose Alpha brass, you can load it up right out of the box and take it to a match.
Here are the cartridges that Alpha offers factory brass in (at the time this was published). They seem to add new cartridges every month. The list very closely resembles the most popular short-action cartridges used in the PRS.
- 22 ARC
- 22 GT
- 22 Creedmoor
- 6mm ARC
- 6mm PPC
- 6mm BR
- 6mm BRA
- 6mm Dasher
- 6mm GT
- 6mm Creedmoor
- 25 GT
- 25×47 Lapua
- 25 Creedmoor
- 260 Rem
- 6.5×47 Lapua
- 6.5 Creedmoor
- 7mm-08
- 7mm SAW
- 308 Win
- 8.6 BLK
I know a few of the top 10 shooters who load up virgin (never fired) Alpha brass and take it to a match. They don’t feel like Alpha brass has to be “once-fired” through their rifle to give them the best consistency shot-to-shot. In fact, you can hear from one of those guys directly:
Austin Buschman is a PRS Champion and two-time IPRF World Champion who uses Alpha brass.
In an interview last year, I asked Buschman what he did before he loads brand-new brass for the first time:
- Do you run your brass through a neck mandrel to set a consistent inside neck diameter? No.
- Do you trim new cases before you load them? No.
- Do you ever neck trim to get more consistent neck tension? No.
- Do you uniform flash holes or primer pockets? No.
- Do you weight-sort or cull any cases that were outliers in terms of weight or volume? No.
Austin Buschman: “No, you don’t need to do any of that with Alpha brass. It’s super consistent.”
Austin only does one thing to brand new Alpha brass before he loads it: “I do chamfer the inside of the necks to avoid the necks damaging the bullets as they are seated. I don’t do this step again unless I trim the brass.”
I asked, “Do you mean you would take brand new, unfired brass straight out of the box, chamfer it, load it, and then take that ammo to a match?” Austin: “Yep. I won 1 or 2 matches this year with virgin Alpha brass straight out of the box. Those matches were close to the start of the year, and I had got new brass at the beginning of the season and was still shooting through all of it for the first firing. The Alpha brass seems to perform exactly the same on the 1st and subsequent firings.” One of those matches Buschman used virgin Alpha brass in was the Leupold Steel Classic PRS Match in Texas, which he cleaned – meaning he didn’t miss a single shot over two days! He hit every target over 176 shots! That was the first and only time anyone had ever cleaned a pro-level, two-day match. That seems to be pretty definitive proof that any extra steps in prepping new Alpha brass may be a waste of time!
Lapua Brass: 24% of Pros
It is no surprise to see 24% of these top-ranked shooters chose to run Lapua brass. That included 2 of the shooters who finished the season in the top 10, including Ben Gossett, who was the 2024 PRS Season Champion.
Lapua brass was considered the de facto gold standard of premium rifle brass for decades. It is a safe bet that more world championships have been won with Lapua brass in Benchrest, F-Class, and other precision centerfire rifle shooting disciplines than any other brand. Before Alpha Munitions, most serious competitors might argue there really wasn’t even a close second compared to Lapua brass quality.
There are veteran reloaders who would still argue that Lapua makes the best brass. I haven’t seen any objective, independant research that compares quality or consistency between these manufacturers, but clearly, Lapua is still extremely capable.
Lapua has added several new factory case options over the past 10 years that are relevant to this group of shooters, like the 6mm Creedmoor and 6.5 Creedmoor – and, this year, the 6mm GT. But they still don’t offer as wide of a range of cartridges that are popular among the top shooters in the PRS as Alpha Munitions. Most notably, Lapua doesn’t offer factory 6mm Dasher brass, which is by far the most popular cartridge among the pros. They also don’t currently offer any 25-caliber brass, which is becoming increasingly popular in the PRS. In general, it seems like Lapua lags behind other manufacturers in terms of adding new, popular cartridges to their lineup.
However, Ben Gossett and a few others were using Lapua brass out of their 6mm Dasher. In that case, they would start with 6mm BR Norma brass from Lapua and then fireform that in their chamber. After one firing in their chamber, they could load it like normal 6mm Dasher brass. The headstamp would still say “6mm BR Norma,” but with the extra fireforming step, it can be used in a Dasher. (Learn about fireforming)
Here are the factory cases that Lapua currently offers (at the time this was published):
- 222 Rem
- 223 Rem

- 8×57
- 338 Lapua Mag
- 338 Norma Mag
- 9.3×62
Peterson Brass: 7% of Pros
7% of these top-ranked shooters were using brass made by Peterson Cartridge, including a couple in the top 25: #16 Keith Baker and #17 Andy Slade. The popularity of Peterson brass among pro shooters has been steadily growing over the past couple of years.
Andy Slade won the $30,000 prize at the 2023 AG Cup using Peterson brass. The AG Cup is a unique, 3-day precision rifle match featuring the biggest cash payouts of the year – which always attracts the best shooters in the world to compete. So clearly, Peterson brass is capable of winning at the highest levels.
Peterson offers a wide variety of factory cases, including 6 Dasher and several other popular cartridges among these pro shooters (e.g., 25 Creedmoor). Peterson’s list of cartridges is significantly longer than both Alpha and Lapua, including a few cartridges that are popular in Extreme Long Range (ELR) shooting:
- 22 Creedmoor
- 6mm BR Norma
- 6mm Dasher
- 6×47 Lapua

- 375 CheyTac
- 408 CheyTac
I will add that if you’re interested in learning how brass is made, Peterson has a great page that walks you through that with visuals.
Hornady Brass: 2% of Pro Shooters
Finally, there were 4 shooters who said they primarily run Hornady brass at matches. However, those 4 were all ranked 101 to 200 in the 2024 PRS Season in the Open Division.
Hornady offers brass for a TON of cartridges, so I won’t list them out here. (Full list of Hornady factory cases)
I will mention that Kahl Harmon, who was the 2023 PRS Season Champ and finished 2nd in the 2024 season, told me that he sometimes uses Hornady brass. Kahl is on the shooting team for the US Army Marksmanship Unit (USAMU), and USAMU ballisticians load all of his match ammo. Kahl told me some of his match ammo is in Alpha brass, and some is in Hornady brass.
That brings up a very good point: If you gave golden bullet winners like Kahl Harmon, Ben Gossett, Austin Buschman, Austin Orgain, or Clay Blackketter ammo that was loaded with Starline or Remington or ANY OTHER BRAND brass – they are still going to outshoot 99.99% of the rifle shooters on the planet!
Articles like this aren’t trying to imply causation. I’m not saying the reason these guys finished on top is because they used a certain brand of brass. It’s simply one component that plays into the precision they are able to consistently achieve at national-level matches. At the very least, the brass they are using isn’t holding them back. At most, it is helping them gain a very slight edge in terms of hit probability through more consistent muzzle velocity and/or improved groups.
Keep in mind that many of these pro-level PRS matches are won by just 1 or 2 points over two days of shooting. Specifically, 21 of the 41 pro matches in 2024 were decided by 2 points or less! In fact, 7 of those were ties that had to go to the tiebreaker stage to determine the match winner! So these guys are trying to find anything they can to boost their hit probability – even if it is by fractions of a point because the game has become so competitive! (More on that in an upcoming article!)
Brass Primer Size
A few of these manufacturers might offer brass for the same cartridge with the option for primer pockets made for either a Large Rifle Primer (LRP) or a Small Rifle Primer (SRP). A popular example is the 6.5 Creedmoor. The original 6.5 Creedmoor case design from Hornady had a large rifle primer, but Alpha, Lapua, and Peterson are all offering 6.5 Creedmoor cases with a small rifle primer or a larger rifle primer.
I was curious how many of these top-ranked shooter opted for one or the other, so I did some analysis on it – and it’s pretty conclusive!
98% of these guys were running brass with small rifle primers! Only 3 people were running large rifle primers, and none of those were inside the top 100. In fact, 2 of those using a large primer were shooting a 308 Win in the tactical division (but still shot well enough to finish inside of the top 200 in the open division). So, if you were wondering if you should buy the brass with a small rifle primer pocket or large – this group seems pretty definitive on that!
I will add that I’ve heard guys from Hornady say if you are using a Creedmoor-sized case in cold conditions (below freezing), they would highly recommend a large rifle primer. They say you could experience ignition problems trying to light powder in those cases that have over 35 grains of powder with a small rifle primer. I personally competed with a 6mm Creedmoor for 5+ years and easily fired 10,000+ rounds with a small rifle primer in it without a single ignition issue – but very few of those rounds were fired below freezing. The guys at Hornady are experts, and that is only my anecdotal experience. But I just wanted to present a balanced view.
I’ve also heard Jayden Quinlan, Hornady’s Senior Ballistician, say that in their research, they’ve found no precision or consistency advantage to small rifle primers. He also hadn’t heard of any other serious research that had been done by other labs that would indicate some intrinsic benefit from small rifle primers for precision.
One reason many of these shooters opt for small rifle primers is the belief that more material at the base of the case could either extend brass life or possibly support slightly higher pressures. I would also bet that some people do believe that small rifle primers are potentially more consistent and might help precision. But, again – I haven’t seen any serious research (based on appropriate large sample sizes) that seems to support that conclusion. So I can’t confirm or deny that. If anyone is aware of research into small rifle primers vs large rifle primers, please share it with us in the comments!
I plan to share more on primers these guys are using in a future article, but I thought at least mentioning what size the primer pocket was would be relevant to this article on brass.
Street Price
I thought it’d be helpful to show the current street price of each of these brands of brass. All four of these manufacturers sell 6.5 Creedmoor cases, so that is what I pulled the numbers for from major online distributors.
You can see Hornady is the lowest priced and Lapua is the highest. Alpha and Peterson are very similar in that middle ground between the two. Pricing will vary by cartridge, but this should give you a rough gauge of how these are priced relative to one another.
Brass Popularity By Cartridge
Finally, here is a breakdown showing what brand of brass shooters were using based on the cartridge they were using at matches.

If one of my close friends was getting into this sport, my advice would be to simply find their cartridge in the list above and buy 500 pieces of brass from the same lot for whatever brand is most popular for their cartridge. If you did that, brass certainly wouldn’t be the thing that was holding you back! 😉
To be clear, not all of the cartridges above are available from the factory. For example, notice the table says 42% of those shooting a 25×47 Lapua were using Lapua brass. Lapua doesn’t currently offer ANY 25 caliber brass. So what those guys likely did was buy 6.5×47 Lapua brass from the factory and necked it down to 25 caliber before fireforming it in their chamber (or you could neck up their 6×47 brass). That is why I included the list of what factory cartridge cases companies like Alpha, Lapua, and Peterson offer in this article. If you don’t want to wildcat brass, then find one of those manufacturers who offer the cartridge you’ll be using.

Very enlightening, a good read!
Thanks!
Hi Cal:
Brass is always a interesting subject.
I had some problems with 500 new pieces of Lapua Brass that were all from the same Lot. The problem was approximately 30% were fat. To be clear I am not saying anything bad about Lapua, I simply just got a bad lot.
But for the first time, I decided to tried Alpha Brass.
I didn’t know anything at all about Alpha Brass. So I emailed the company and asked if they were comparable to Lapua. They didn’t tell me they were better, they just asked me to try their brass and report back to them what I thought. So I tired it and I liked it.
Your article today proves Alpha Brass is high-quality brass.
I was very surprised that Hornady made the top 4. I consider Hornady brass to be average, in the same class as several different lower grade brass.
I also think its very normal to think you should be able to load high-quality virgin brass without doing anything to it. That one of the things I expect from Alpha, Lapua, etc.
Good article, thanks
Paul
Hey, Paul. Thanks for sharing your experience. Honestly, I’m not surprised they didn’t tell you they were better than Lapua. It’s a pretty humble group of guys at Alpha. But they are confident in what they do, and they think if someone will just give it a shot – they’ll become a fan.
It reminds me of when I first met those guys back at SHOT Show 2016. They were just getting started. I don’t think they’d be operating a full year yet. Not long before that I had published my massive high-end scope test and then my muzzle brake field test. Those were both 400+ hour, very objective/empirical, first-hand, independent research. Nothing like it had been done at the time, and I haven’t seen anything since in the public realm that is as comprehensive and technical. There just isn’t a lot of head-to-head comparisons done like that, because someone always ends up the loser.
That is why the team from Alpha Munitions sought me out. They basically found a way to contact me, and asked if I’d meet with them for a few minutes at SHOT Show. They were hoping that I’d do the same kind of objective, head-to-head comparison of their brass compared to “other premium brands.” In 2016, Lapua was absolutely the gold standard (and some still would argue they are today) – so I asked them directly if they thought it was as good as Lapua. Like they did with you, they aren’t going to toot their own horn … I think they just said that they’d be excited to see how I thought they compared. I will say they were very confident any objective tests would be very favorable for them. They were very confident in their product, but didn’t say anything about other manufacturers.
The founders of Alpha gave me 20 pieces of 308 Win brass there at SHOT Show, and when I got home I tried to think of ways that I could test it against Lapua, Norma, Nosler, Hornady and other popular brands. I thought an objective brass comparison would be very interesting, but to reach any conclusions that would be statistically meaningful – it would take a massive sample size. I think you’d be north of 1,000 rounds fired. There is just so much going on when a round goes off that it is extremely difficult to isolate variables. In fact, it’s impossible to isolate variable – but you can possibly detect the impact one component has if you have a massive sample size to help separate the signal from the noise. I also thought for the results to be meaningful, you wouldn’t just need to do it on one lot of brass – but on multiple lots. Like your experience with some bad Lapua brass, that is something that every company faces. Consistency is HARD! There will be some natural variation in the quality of products that leave any factory, so you can’t just get one random lot and assume it is representative. Then I thought actually a manufacturer could be great at one cartridge and maybe more sloppy with others. So you would need multiple lots over multiple cartridges! Now we’re likely talking well over 10,000 shots fired.
So, unfortunately – I couldn’t figure out a way to empirically compare brass at the time. I will say that I still have a bunch of notes from that and think about it occasionally. Maybe one day I’ll take a stab at part of that for at least one cartridge, like a 6.5 Creedmoor. It might not be until I retire or something, because it would be a massive undertaking.
I will say that this “What The Pros Use” data is based on experience of shooters who have launched A TON of rounds downrange. I’d bet the average shooter in the top 200 fires 2,000-4,000 rounds annually. I know some of the guys in the top 25 are 6,000-10,000, but I’m sure the majority are lower than that. Austin Buschman told me he knows he averages somewhere around 6,000-7,000, because he gets a new batch of 1,000 pieces of brass every season and typically loads it 6-7 times. Hey may lose a few pieces along the way, but he also shoots some other rifles through the year. And Buschman shot 11 pro-series PRS matches in 2024. Several others in the top 25 competed in 15 matches! I finished 99th overall in the 2024 PRS open division, so I’m personally among this group represented. I haven’t added up all the rounds that I fired in 2024, but I would suspect it is around 4,000 rounds fired out of a precision bolt action rifle. That included 6 regular season two-day, pro-series matches + the PRS Finale.
If we say that the average shooter in the top 200 shot 3,000 rounds in 2024, then that means this group shot 600,000 rounds – just this year! This wasn’t the first year I’ve fired that many rounds either! You don’t get in the top 200 if it is your first year shooting a bunch of rounds. I think it’s very likely that this group of 200 shooters has collectively fired 2 million or more rounds out of precision bolt action rifles over the past 5 years. If you think about that collective sample size, that is massive! And like me, many of them have tried many of these different brands of brass. I’ve personally shot 8,000+ rounds out of Lapua brass, 8,000+ rounds out of Alpha brass, 8,000+ rounds out of Hornady brass, and 8,000+ rounds out of Norma brass. And while this “What The Pros Use” data isn’t based on empirical, independent research – it does represent the collective knowledge of that group of 200 shooters who are VERY EXPERIENCED! So while it isn’t the research I was hoping to conduct, it might be a shortcut or at least some indication of what head-to-head research might reveal.
As far as Hornady goes, I figured that might have surprised a few people. Keep in mind it was only 4 people out of 200. One of those was Joe Thielen, who is an outstanding shooter. Joe finished 2nd overall in the Tactical Division shooting a 308, but still placed 103rd in the Open Division. That is pretty outstanding. I was using a 6mm Dasher and placed 99th overall in the Open Division, so honestly Joe is probably a better shooter than I am. Joe is also the Hornady Assistant Director of Engineering. So I guess I’m not surprised he uses Hornady brass. I don’t think the other 3 were Hornady employees, but that at least accounts for one of those. Now, I’m not dismissing it either. Joe used Hornady brass to compete at the highest level. It is obviously capable of competing at that level. But that does put a little * by it in my mind.
As I was looking through the data just now to try to reply to this comment, I was thinking that I knew of another Hornady employee that placed really well … but then I thought he may not have made the top 200 this year. But, I did find his name in the results … but he wasn’t using Hornady brass. I don’t want to throw the guy under the bus, so I won’t mention his name. I can say he was using a cartridge that Hornady makes brass for – but I guess he simply chose to buy Alpha brass to run at matches. I don’t blame him! In my humble opinion, Hornady brass is a great value and it will do great for the majority of shooters out there … but it’s not in the same class as Alpha or Lapua when it comes to precision rifles at a competitive level. I think that is just the truth of it.
But then again, is that a bias sneaking in? Would empirical research prove that out or would be surprised by how some brass stacked up against other brands? Ha! 😉 That’s why one day I’m sure I’ll break down and do that brass test. It would be so interesting! I would bet there are some surprises in there. That just means people on the internet will probably dismiss it, or claim it was rigged. In my experience, anytime you ever do serious, like double-blind research … you are going to come across more than a few surprises. Every research project I’ve been part of raises as many questions as it answers. In fact, if you can explain all of the data and it perfectly fits whatever preconceived theories the larger shooter community has – then you can know for sure the data was doctored. I’ve talked about that a few times with Bryan Litz and the guys at Applied Ballistics. It’s just the truth of it!
Sorry for the long reply! You just got me thinking! 😉 I appreciate the comments!
Thanks,
Cal
I spoke to the manager of Federal’s primer manufacturing because I had some questions regarding the compound used in their GM205MAR primers (they use the same compound as GM205) and he told me that they found they got better consistency with small rifle primers in their center-fire rifle cartridges. It might be worth reaching out to Federal and see if they have any research they can share with you.
Very interesting! Thanks for sharing. I don’t know anyone at Federal, so could someone share a contact?
