RCBS - PRIMER POCKET BRUSHES

Gives a great result chucked in my B & D 18 volt drill driver Very long lasting if used with care but bear in mind after cleaning many thousands of pockets these eventually wear out Cheap enough to buy a few replacements Much better result than using the fixed scraper tools and brass or bristle brushes

Having used them all, and still using both large, and small, wire brushes, they're my goto for cleaning primer pockets. I have to order another small after over 10 years of heavy use. The large one is still going strong. The small brush started losing it's outside bristles due to my being in a hurry, and not insuring that the bristles entered the pocket fully. They flare out when that happens, and have to be cut off to allow the remaining bristles to fully seat in the bottom of the primer pocket. They'll still work with missing bristles, but it takes more time to fully clean the pocket. I mount the brushes in my drill press chuck, and run the brushes at medium speed. It takes less than three seconds to fully remove all carbon from the pockets. There's nothing faster. Wet tumbling, with stainless pins, works well, but takes far more time. The serrated scrapers work OK, but always leave traces of carbon, and take far more time. The brushes work best at higher speed. Doing it by twisting a tool by hand is a miserable task, and takes a lot of time. The brushes, running in a moderate speed drill press, is the fastest, and most thorough, cleaning method I've found in 55 years of reloading.

I use the large brush for both large and small primer pockets, it doesn't matter. The large fits the small primer pockets perfectly, but not so much the large pockets. For the large it always leaves the outer edges untouched so you have to really work it around to get the outer edges in there clean.
