Who makes one that is adequate for the 50BMG?

Maytag

When I was in the USAF in Nebraska (1980s)one of the guys had a side business (ffl). I went to pick up my Dan Wesson one day, he had a small cement mixer going, his partner was shoveling empties into it.

Appears to be about the right size!

we've been using a small cement mixer for awhile now. works great, but use it outside because it makes a fearsome amount of dust

A gent on another forum lucked into a huge amount of brass, like 55 gallon drums worth. The Harbor Freight cement mixer was his answer to tumbling to clean the cases prior to sale. Frank

I cleaned 10K cases using brichwood casey case cleaner.
Get the brass warm in the sun, fill a 5 gal. bucket, let sit for 5 min, remove, rinse in clean water, and dry in the sun.
Phosphoric acid is the main ingrediant.
worked for me.

This set up, using a 40 lb. production tumbler, (Covington Engineering brand), from Stainless Tumbling Media of Orem, Ut, along with 15 lbs. of their stainless steel pins should perform quite nicely for the .50 caliber brass. Just add water, Dawn dish washing detergent, and Lemishine polisher, and you're set to go. Cheers. chip.

I've always used the usual tumblers for 50 bmg. My RCBS would hold 20 and my Thumbler tumbler (water, stainless media) holds 30 at a time. they work just fine .

The large Dillon 2000 is great.
