Sorry if this is a repeat question but I couldn't find the right question in the forum history. I just started reloading for my .223 and things were going good until I got a case stuck. I pulled out the primer removal pin in fear that I might hit it with the drill bit...well I got the case out and put it back together and started FL sizing again. After a few cases I inspected one and noticed a bulge in the case where the neck meets the shoulder and it kinda looks like the mouth is smaller then the cases that I resized before the case got stuck! Any ideas on what I screwed up?
