Brass Cleaning

[winmag]

Hey Woods, what is that little (or not so little) belted case and caliber? I cant figure it out from the pic.

The first 2 pics are 300 win mag and the 50 cases in the loading block are 338RUM.

An utlra sonic unit with heat is the best way I have found. I use 50/50 water and
vinegar, tablespoon of lemi-shine, and a dish soap with ammonia laurel sulfate in it.
They come out spotless inside and out.

Where did you get your ultra sonic ? Can you stack the brass in it or do you have to just lay them down ? I would like to get one that would do 100 rounds at a time. In a 7mm or 338.
