[quote="Laurie] I'm currently doing a three part test / review of SR primer performance in Target Shooter online with parts 1 and 2 published and the conclusions / results in part 3 going live in the next week or 10 days.

If you look at Part 2 you'll find a pic of some Rem 6 1/2s which have nearly failed in a 308 Win 'Palma' brass load which QuickLOAD estimates at around 58,000 psi - some 4,000 below SAAMI maximum. The CCI-400s produced examples that had cratered almost as badly. Other models either cratered slightly or showed no damage at all. These were fired in a rifle with a Stolle Atlas F-Class type action that will reduce metal stress through lack of cup support much better than many factory actions[/quote]
Bookmarked ready for part 3.
Good read.
