Let’s start with wall thickness. A key to consistent bullet release upon firing is even neck tension. One of the best ways to achieve this (along with careful brass preparation) is to start with as even a wall thickness as possible. My measurements have indicated that Peterson runs right at .015” neck wall with minimal variation. This dimension works well across my platforms. If you decide to turn the necks for specific applications, there is plenty of brass to work with.
Case expansion is inevitable, and one of the first places it is observed is the primer pocket. For me there is nothing more frustrating than preparing brass only to find an oversized primer pocket near the end of the reloading process. A strong case head, leads to more reloads with the same brass. To date I have Peterson cases that are approaching 10 firings with no issues of loose primers. Starting with strong brass and following safe loading procedures help me increase the life of my brass.
How does it perform? This data is from a recent range test.
- Peterson Match Grade .308
- Federal 210m
- IMR 8208 XBR
- Berger 155.5g Fullbore Bullet
- Velocity 2975 FPS from a 30”– This load produces extreme velocity spreads of <10 FPS for 20 rounds.
- Results 4 of 5 in the same hole at 100 yards.
Stay safe, and we’ll see you on the range.
