[QUOTE="YZ-80, post: 2007312, member: 109229"] I can relate. If you follow the RCBS set up instructions you'll bump a case .005 to .007" in a heartbeat. I've done it for years with no ill effects and better than average accuracy out of my stuff but I'm told it is hard on the brass and can lead to other problems (so can Bourbon). Anyway, now I try to keep the bump at .002" and that seems to work great. Sometimes, the problem can be brass-specific too (or related to the lack of annealing). In a recent situation with Hornady brass, I had some new stuff that would not chamber after resizing, even with a healthy cam-over. It simply would not bump the shoulder enough for me to cam the bolt shut. I explained this to reloading "expert" and he told me I had a tight chamber. I slapped him across the face for getting fresh and left his establishment, taking my business elsewhere. [/QUOTE]
