Reloading .303 British : Cleaning brass

I have an old Lyman Orange vibratory tumbler & I use walnut media. A couple of hours is all it needs you don't need to polish to a high gloss, in fact some don't like that as its thought too slick isn't good.

I separate the media with a home brewed gadget involving a couple of plastic colanders. I clip & zip tie them together to make a mesh "ball" & just rotate it by hand over a 5-gallon pail to collect the media.
