Best Bullets, Powder & Brass – What The Pros Use 2013

This post is about the bullets, powder, and brass the best precision rifle shooters are using. It is based on what the top 50 long-range shooters nationwide brought with them to the Precision Rifle Series (PRS) Finale a couple weeks ago. Target engagements for a PRS match can range from 25 to 1,200+ yards, but there is definitely a focus on the “precision” rifle part regardless of the range. For more info on who these guys are, and why you should care what they think scroll to the bottom of this article. Update: These are results from the 2013 PRS Season. The ...

Precision Bullets & Powders: What The Pros Use 2012

Meet The Pros The Precision Rifle Series (PRS) is a championship style point series race based on the best precision rifle matches nationwide. PRS matches are recognized as the major league of sniper-style rifle matches. At the end of each year, the scores from 15 different matches are evaluated and the top 50 shooters nationwide are invited to compete head to head in the PRS Finale Match. The info below is based on the equipment those pros brought with them to the most recent finale. This is a great set of data, because 50 shooters is a significant sample size, ...

Rifle Reloading Data: My Pet Loads for Target & Hunting

These are some of my pet loads. They were what I found to be the most precise in my rifles after extensive and tedious load development. I may tweak the loads slightly as the throat of a barrel erodes, but I don’t typically vary too far from what is shown here. You should always reference a quality reloading manual and start with the minimum recommended loads and work your way up. Just because these have proven safe in my rifles, doesn’t mean they will be in your’s. Chamber dimensions, brass specs, barrel grooves and diameter can vary, so it’s very important ...

Berger Bullets Bearing Surface Variation

One of my friends recently told me they sort bullets by both weight and length of their bearing surface (the part of the bullet that comes in contact with the barrel, illustrated below).  I hadn’t thought of that before, but you could see how variations in the bearing surface length obviously impact the amount of barrel friction on the bullet and therefore cause variations in muzzle velocity. For virtually all of my precision shooting I use Berger bullets, and I wondered if there was even any measurable variation in their bearing surface because their quality control is so much tighter than other ...

7mm Rem Mag Load Development Part 3: Optimal Charge Weight

After I identified a promising range of powder weights using Audetter’s ladder test, my next step was to use Dan Newberry’s Optimal Charge Weight (OCW) Method to offset the “scatter node” drawback inherently present in the ladder test.  To learn more about that, read this article comparing the OCW method with the ladder test. The OCW method is based on the observation that there are some loads out there (like Federal’s match ammo for the 308) that shoot really well out of just about any rifle.  How can one recipe shoot so well out of so many different rifles?  Dan Newberry believes accuracy of ...

7mm Rem Mag Load Development Part 2: Audette’s Ladder Test

The first step in load development for my new custom 7mm Rem Mag started with gathering the real-world velocities I could expect out of three quality long range bullets I was considering. I then used those velocities to compare the ballistic performance between those three bullets, as well felt recoil during the test rounds. I eventually decided to pursure further load development for Berger’s 168gr VLD bullet over Hodgdon Retumbo powder because it struck the right balance for me between the competing characteristics (recoil, barrel wear, flat trajectory, low wind drift, ideal energy for medium sized game, etc). For more ...

7mm Rem Mag Load Development Part 1: Bullet Selection & Real-World Velocities

The first step in load development for my new 7mm Remington Magnum (with a 27″ barrel) was to get a basic idea for the real-world muzzle velocities I could expect out of a few different high quality, very low drag bullets, so that I could compare them ballistically and decide which to pursure for further load development. I decided to try out the three bullets listed below after reading a great article on 7mm bullets by Nathan Foster. I actually took all of these readings with a BRAND NEW BARREL (some of the first rounds out of it), so they ...

Custom 7mm Rem Mag

I recently had a custom rifle built that was chambered as a 7mm Remington Magnum. I plan to use it as a dual-purpose rifle: Precision rifle matches (target shooting out to 1000 yards) Hunting (primarily whitetail & mule deer and the occasional wild hog) I did a ridiculous, almost embarrassing amount of research before landing on the 7mm Rem Mag cartridge. After losing a deer last year, I wanted to make sure it had enough energy to put an animal down quickly. There is no such thing as overkill. With that mindset, I actually started by looking at the 300 ...

Creighton Audette’s Ladder Test

Creighton Audette came up with a method for developing precision rifle handloads that has been referred to by many names: Incremental Load Development Method (ILDM) The Ladder Test 20 Round String Method Unfortunately many of Audette’s original articles aren’t very accessible, so I wanted to provide a few resources that help flesh out the method to load development he proposed.  I recently tried it out, and although at first I admit I was a little skeptical … after seeing the real world results and some critical thinking about what we are really trying to uncover when doing load development, his ...

Berger 7mm 180gr VLD Bullets Weight Variance

Like most things in handloading … the more uniform one round is to the next, the more uniform ballistics you can expect.  That is why I weight sort my bullets, and for my match grade ammo I only load bullets that have exactly the same weight (+/- 1/10 grain). I recently weight sorted a box of Berger 7mm (.284) 180 grain Match Grade VLD Hunting bullets, and here are the results: Average = 179.89 grains Standard Deviation = 0.085 grains Extreme Spread = 0.4 grains Extreme Spread as % of total weight = 0.2% (this is amazing) Bullet: Berger Bullets 180 ...
