Something I've never done in 35yrs of reloading, other than buffing the outside of the cases, so my ignorance on the subject is that of a "newbie". For you who do it, do you use tumblers or rotating drums? Which does a better job? What is the best media to use to get the inside of the cases really clean? Do you add liquid cleaner to the media? How do you get all the media out of the cases once they are cleaned? I would think the smaller the caliber, the more difficulty to be had with this part of the operation. Air compressor with blower? Thanks.
