[QUOTE="Buster Hemlock, post: 1643877, member: 109327"] Hespco, I'd really get away from the bronze brush inside the neck. Your putting scratches inside the neck, possibly wearing the insides of the neck unevenly and there is no way they are uniform across all your brass. Uniformity is the name of the game. Those scratches and non-uniform necks turn into varying amounts of grip on the bullet within the neck which will result in different amounts of uncorking pressure, thus greater SD and ES. I'd switch to nylon if your going to continue this practice, which will still accomplish the polishing your going for. Also if your storing your loaded rounds for any amount of time a little carbon left in the neck or the application of some graphite with a q-tip will help eliminate cold welding of the brass and bullet jacket.
