I recently bought 100 cases of fresh new .45 Colt brass and decided to do a little reloading. When I started to prime the cases with CCI large pistol primers using my Lee priming tool I was unable to seat the primers without using both hands and a great deal of force. I chamfered out the pockets on five cases and with some force I was able to seat the primers. Has anyone had this kind of problem with Starline?
