I tried it on my new Winchesteer brass and just broke the sharp edge of the primer pocket, "issue" vanished.
Laurie loaded .308 Acquire ammo* with 16 LR primer kinds and then tested for average velocity, ES/SD, and group sizing. This may be the most in depth and comprehensive LR primer test at any time completed. Listed below are the primer kinds tested:
I will provide the Federals a test as I don't load near max anyways. I like to help keep my hundreds in the center. Assuming that I'm able to shoot good teams and put holes in the paper I am happy, additionally I feel it's less annoying on the firearm plus much more pleasing to shoot.
so do as you believe most effective. Should you be firing the M1 Garand I'd propose using "army" primers as they are greatest for that firearm.

A number of people could have guns like my revolvers with light-weight hammer springs. Without doubt, reliability and precision troubles will exhibit up when primers with more difficult or less delicate cups are utilised. In the course of my exams, I found If your hammer did not strike the primer challenging enough .. it might make the primer detonate with way less flash. This leads to poor powder ignition or perhaps a click on-no bang. When hammer energy is robust ample for any good stable primer strike, you will find just about no difference within the flash between brands.
Laurie’s results will doubtless affect numerous hand-loaders who hope to provide extra steady ammunition, or accomplish better precision. Credit rating must also be presented to focus on Shooter Magazine for publishing the outcomes. Perfectly performed gentlemen…
One thing which i do persist with is: when loading for my M1A and AR I take advantage of 'army' primers. Especially in the M1A. My being familiar with is the 'civilian' primers are too gentle and market the notorious 'slam -fires'

Add to estimate Only show this person #five · Dec 2, 2024 I have shot many CCI ammo in a number of 9mm guns, in no way a misfire. I do have a pair revolvers that have lowered ability springs, I have expert a misfire on at the least one of these working with apart from Federal primers.
