Re: Which tumbler or ultrasonic cleaner to buy?
A Rockwell hardness tester tells me that SS cleaned brass is not work hardened from the cleaning, my chronograph tells me that dirty brass has lower SD/ES, I found that ultra clean brass needs some sort of lube to aid in bullet release, so I lube my the necks of SS cleaned brass with graphite powder, also the lips of the brass get peened from SS cleaning, no biggie for me because I have a Giraud Trimmer, but if I was still hand cranking I'd be pissed, so my recommendation is to start off with a vibration tumbler and use walnut shells from the pet store, add a little NuFinish car wax to the media and spend your money on other things for the reloading bench.
