It is clearly tumbling in stainless media.
I hadn't cleaned my octane in a year and I've shot hundreds of 45 through it including steel case, countless 9mm, full auto 9mmm mag dumps, and about 100 rounds of 44 magnum. This is how clean it is after I let the baffles tumble last night.
And the blast baffle, which had been exposed to some pretty fast burning 44 magnum powders.
Prove me wrong.(Pro tip: you can't)
