[QUOTE="jsimonh, post: 494815, member: 26029"] I'm getting great info from you guys, thanks! I use a RCBS precision mic every time I reload. I sized the brass because it comes in a bag and had necks that were visibly out of round. Normally I'd just lee collet neck size them, but for some reason I decided to body and neck size. As I stated earlier it was only about 5 out of 30 that had this problem. When I resize fired brass I only bump the shoulder back about .003, this new brass was a lot furter back then that. I don't have the numbers in front of me, but I think it was someting like .020 shorter then my resized fired brass. This particular set of shells had the bullets set back .020, and I measured everyone at the ogive to make sure. The first time I shot and had this problem (68gr) I never tried to extract a loaded round back out. Thats why I was assuming I was having pressure problems. When I had the same problem at 67gr I began chambering and then extracting each shell, then re-chambering it to shoot. Only a hand full were hard to extract, and they were equally tuff to extract after firing (the 5 that stuck not all of them). [/QUOTE]
