Ok, maybe I sipped too much of this SS wet tumbling kool-Aid but here's a test I ran last night for sh!ts & giggles.
Here's some 2x fired 308 cases that were cleaned with green cob media for 3hrs. Brass is nice and shiny on the outside and looks clean.
Dumped cases into my $29. HarborFreight rock tumbler with roughly a tablespoon of dishwashing soap, a pinch of Lemi Shine, 3/4lb of SS pins and filled with hot water just below the top of the cases. The drum on the right are previously media cleaned 357Mag cases.
Tumble for 3hrs.
This is the dirty water that comes out at the end from previously cleaned media tumbled cases.
Silly me didn't think about this at the start but next time I'll do a volume weight test on a single case. I don't think there will be a significant change in volume from cob to ss tumbling but would be interesting to see.
I'll probably stick to media tumbling for my plinking ammo cases since I wouldn't have to wait for them to dry before sizing them etc.
