[QUOTE="Ballistic64, post: 132638, member: 3401"] [ QUOTE ] Not sure how to officially check that, but they appear to be OK. I may have figured out at least part of this problem. Tell me what your opinions are of this. New case from base to shoulder (using a comparator) is 3.990" Fired cases are 3.993" I had been bumping the shoulder back to 3.988" Do you think that has anything to do with this? Should I be setting the shoulder back any at all or less than I have been? I have already reset my die to bump it back only 0.001". Will see if that helps any. [/ QUOTE ] Sorry to ask the obvious,but are the cases within the trim to length spec? Bumping the shoulder back .005" does sound excessive.With the gun Im shooting I usually bump the shoulder back .001 after every other firing.I turn also and have checked my neck wall thickness after firing the cases six times with no increase in the thickness and these are RP cases.The only dimension Ive had increase is the OAL of the case itself.Be interesting to see what you find.
