[QUOTE="dok7mm, post: 2316525, member: 90080"] FYI - The case should fill your chamber on firing, then reduce slightly on cooling so you can extract the case. Your brass should be bumped ONLY about .002" to .003", so it will chamber easily but not too much bump. If you bump too much you are causing the brass to stretch on every firing, thinning the brass at the case head or just above and it will separate. With calipers and a Hornady gauge (there are several more brands) you can make your brass last longer and be safer. And yes, I would pull the bullets from your brass and check for thinning near the base. A paper clip can be straightened, bend an L on the end and sharpen that tip. Run it down the neck and feel for the deeper ring above the base. You probably need to junk the brass, but you'll learn by checking. Glad you came out safe. If you have a borescope, check your chamber for damage. Seekins will probably do that though. [/QUOTE]
