Ive got the same problem in a 6 dasher, I tried a smaller base die, using a 308 die and it didnt help. havnt solved it yet, but getting closer. I tried a different jug of powder, the one i was using was 15 years old, using one now thats only 5 years old. it did help, but still got clickers, just not as bad. the SAC die IMO is worth the money, there really nice, got it thinking mine wasnt sizing the .200 line enough. whats got me puzzled is the pressure signs on the head of the brass with a load thats 250 fps less than everyone else is running. 2 1/2 grains less powder. no turn neck chamber thats plenty big, .275. loaded round is .268. peterson brass, 29 gr of varget at 2720fps shows ejector and extractor dents in the brass. node is at 31.4 with deep marks in the brass and hard bolt lift with the older powder. less than 300 rounds, bullets loaded at touch.
only have the one gun, everything started new. next im trying some alfa brass with the newer powder.
