Re: Brass Cleaning Using Stainless Tumbling Media System-Review
I too love my STM setup. Nothing I’ve seen comes close to getting brass this clean.
In the last step of my process, I throw the wet brass in my vibratory tumbler with Hornady One Shot media. The media never wears out because the brass is clean and in an hour or so of tumbling the brass is bone dry and can be used immediately.
In your list of disadvantages I thought you might mention one that I noticed – rifle brass does get “shot peened” around the mouth of the case by the other brass. This makes it significantly more difficult to seat a bullet if you don’t do a light inside chamber on the case mouth.
A final point - it turns out I live a few miles from Tru-Square that manufactures the Thumblers tumbler that STM sells. Tru-Square sells several different sized drums including a smaller all rubber drum and rollers to snap into the base so the base can be used for either the large or small drums. I bought two of these small drums and now I can switch between large and small drums depending on the amount of brass I’m cleaning. The smaller drums clean up to 30 pieces of rifle brass but in almost half the time compared to the 20 lb drum (2.5 hours versus 4.5 hours) which is why I was interested. I can put two of these smaller drums on my base to clean up to 60 total pieces of rifle brass or if I have more I go with the larger drum.
