Ok quick question for a new guy. Did a quick search and can't really find what I am looking for. Pretty new to reloading but am kind of a perfectionist. I bought an RCBS pocket brush to clean the pockets and it just doesn't seem like it does very good of a job. Still see residual in the crook of the pocket. It also looks like it scratches of the some brass. Seems very harsh and primitive to do it this way. Is it fine the way it is or is there a better way. Accuracy in my hunting loads is my primary goal. Also is the residual on the inside of the case negligable? I thought tumblers were mostly for aesthetics, is this wrong? Also what are your thoughts on Lymans primer pocket reamer? Is this just another reloading gimmick? The idea makes sense to me. thanks so much and sorry for the barrage of questions.
