I just got a RCBS Rock Chucker reloading kit, and today I got it all set up and started going, and everything seemed to go smoothly, but a the end I found that the rounds didn't chamber as readily as factory ammo...and they were a pain in he ass to unchamber...the OD of my final case is just a fraction too big. the dies I am using are Hornady, they were a used set, but didn't seem to show too much wear...is the issue with the OD of the round cased my the deprime/resize die? or is it something going on with the crimping/seating die? or is it a sign of a different issue? any help is welcome.
