Tumbling?

[sargenv]

I don't care for the larger corncob you get at the feed/pet store.. I find that the finer corncob sandblast media is much better for getting into those small places (.223 rem brass for instance). Grainger sells the media in 50 pound sacks for relatively little money.

I paid $38 bucks for a 50 pound sack of 14/20 grit at grainger. It's really really fine grit, maybe a little too fine as it's kinda dusty. But this is what I run in my cement mixer. About 20-25lbs of it right now.

I've gotten over the need to have "shinier than gold" brass. Shiny clean is just fine. This sonic tumbling, or thumblers or washing brass is a complete waste of time and overthinking, in my personal opinion. It's all about QTY. If I can do 3000 pcs. or more at a time, i've saving electricity and time.
