Brass Cleaning Using Stainless Tumbling Media System-Review
Here Are STM Cleaning Results ó Judge for Yourself
Results of STM Tumbling Are Very Impressive
So this is where it all gets interesting. My first batch was a load of pistol brass that I had picked up at the range the weekend before. Here are some photos of before and after. None of the photos are doctored. I didnít do anything other than load brass, soap, water, Lemi-shine, and the stainless media into the tumbler.
Pistol Brass Cleaning
For my pistol brass. I sorted the brass into calibers before tumbling. If you donít sort, the 9mm cases will stick in the .40 cases, and .40s will stick in the .45acp cases. How well did the STM cleaning work? Take a look at the pictures. First is a photo of some heavily-tarnished .45acp brass before tumbling. The next two photos demonstrate just how well this system works. I was amazed! The brass looks brand new. As promised, the brass is clean inside and out.
Rifle Cartridge Cleaning
The next batch of brass I decided to clean was some well-weathered 5.56mm brass I picked up at the range. I was really interested to see how this rifle brass turned out. It would be really nice if the insides were as clean as the pistol brass. A clean interior neck would most likely aid in accuracy. I love the way it feels to slide a bullet into a new piece of brass! As you can see this brass is heavily weathered. I did not do anything special to clean it either. I simply put it in the tumbler, filled it with water, added soap, added Lemi-shine, and tumbled it for four hours. The outcome is basically new brass ó the brass is totally clean, inside and out.
