I am interested in what that tool looks like. Would you mind sharing a picture of it?primer pockets don't need cleaned every time. accuracy nuts frequently skip cleaning them. usually I punch out primers and seat new ones right away. I have a whitail engineering tool [ long discontinued] that fits in a drill that I hit pockets with every few dozen shots. I use the drill on the pockets before the first shot to make sure the pockets are all the same depth.
I shoot hundreds most week ends and I still do it by hand most times as you can inspect each case.
there are several others on the market besides rcbs that the guys seem to like. check out youtoob as I cant say which is better.
