my first attempt at pistol reloading. all went well until i tried seating and crimping bullet. (no primer or powder yet, just dummies). there seams to be a slight buldge in brass at or just below bottem of bullet. this appears as i reach the proper depth with out, or more so with, crimping. is the 180 gn bullet just to long? this is with new remington brass and new hornady 3 die set. thanks richard
