I use a media tumbler for cleaning brass. The most teadious part of this is cleaning primer poctets and inside of case necks trying to get it free of media dust and carbon in primer pockets. It shure would be nice to clean all in one step. I saw the other post about cleaning necks and didn't want to steal his thread. Are the sonic cleaners any good?? I usually get 400 in bass pro gift cards from the inlaws and am getting a RCBS chargemaster and need one other item.
