I switched to Wolf SRM several months ago, couldn"t find BR4s anymore. Bought several thousand and have been redoing all my 6br loads with them. I think the cup is at least as hard as the CCI, and handles similar velocities/pressures about the same. They are noticably larger in diameter than the silver primers, and snug right up in pockets that were getting loose with CCI
Accuracy is terrific, one of my loads is shooting in the .1's, (Berger 95VLD with Varget hard into the lands) and SD is basically the same as I was getting from the BR4s, single digits on my best loads to around 20 with the lighter bullets. Results with Rl15, Varget, and N135 were consistent, all powders had to be reduced from .8 to 1.4 grains with the magnum, but I believe they would be very close with standard Wolf.
I was skeptical until some of the guys on this forum started giving them good marks, but now I think I will stay with them even when supplies return to normal. Also a lot lighter on the wallet than the BR$.
