[QUOTE="Stammster, post: 2387501, member: 114381"] I’m not even sure how it’s possible that the seller bumped back the shoulders that far with a factory FL sizing die. The die should have bottomed out on the shell holder long before he could bump the shoulder back that far. My RCBS dies max out about 2.039” at full camover. Factory is 2.040”, my chamber headspace is 2.043”. I bump to 2.041”, with the die screwed slightly out it just touches the shell holder on the upstroke. I suspect the seller didn’t have the correct shell holder for the die. I have seen some undersized measurements with a comparator if too much lube was used and the shoulder was dented and the angle wasn’t crisp. But if all these are the same issue, you are rightly concerned regarding future case head separation. I say send them back. Blowing out the necks with a mild jammed load is going to cost you another $50 in components, and a bunch of time. [/QUOTE]
