I had the same problem with winchester primers, i have not had a problem since i switched to cci mag, my issue with the hard bolt lift, here is what i found. I usually just neck size with my wilson dies, but i have hade the issue with the bolt lift , and in my case it is the shoulder on the brass. Either my body die or fl size with my redding fl sizer clears that issue up for me. also the bplt on the 25 is not a super stout one, when i get the speed up close to 4000, i get pressure sighns. All in all, my gun shoots in the high 2s so no complaints on the accuracy. Smitty
