[QUOTE="codyadams, post: 1717690, member: 87243"] I see a lot of people use 60 grains as a threshold, and I generally agree!! I have only found a couple of variances to this. In my .260 AI with small rifle primers, igniting 49 grains of Reloder 26 under a 156 Berger, I was using the BR-4's because they produced the best results with the 147, but found out with the 156 they had erratic velocities, like 50+ fps e.s., and s.d. #'s in the high 20's. Switched to cci small rifle mag primers, and boom, e.s. #'s in the teens and single digit s.d.'s. My point I guess is, it never hurts to test different primers, to see what the most consistent results come up with. I have been surprised a couple times!! Ha ha. [/QUOTE]
