AR's as well.
I expereiced similar results when I mistakenly purchsed 100 SR primers instead of small pistol. In mild 40S&W loads ,ca 775-800 fps, with 155 to 180 gr jacketed bullets the SR spriemrs gave ca 20 fps more velocity than the same brand SP primers.I've been going through small pistol primers like water. Having a number of small rifle I wanted to see what the results would be.
Loaded up some 9mm FMJ with my normal data (4.5gn Titegroup) and ran them through the chrono. Results were 20-30fps faster.
Loaded some lead with 4gn of WST and found 20fps faster.
No case stresses, no case damage of any kind. With such a minimal chance in velocity, I feel safe in loading my pistol the surplus of small rifle (5.56) primers I have.
I wanted to post this because I read on a number if forums a variety of opinions with out any real world experience.
My experience has been good for the first 500 rds of testing.
Anyone else have input?
