Cleaning primer pockets is a waste of time.
...so is tumbling, trimming, neck sizing, cleaning flash holes, neck turning, checking run-out and weighing....but hey, removing as many of the variables as possible can't hurt.
Cleaning primer pockets is a waste of time.
I'll have to disagree on this point. IMHO money spent on a tumbler is money well spent. I realize there are other manual labor intensive ways to clean brass, but the tumbler does a good job. Dirty brass can scratch your sizing die, or worst your rifle's chamber.
