re: Problems with Tula Ammo?

Once, while in the presence of a buddy of mine, I experienced the problem and he said, "You need to run a little brass in every mag to keep it cleaned out."

That didn't make sense to me. How did brass keep the action clean? Besides, common knowledge was that you never mix steel and brass when shooting...that mixing the two would only make this problem worse.

Then I read this article on the Box O' Truth LINK about steel case and brass cased ammo. Although their hypothesis confirmed my friend's statement that brass ammo could help clean the chamber, they stopped short of recommending (or figuring out) that running steel and brass together can make a gun run more reliably.

I figured it was up to me to test it.

I started by cleaning the chamber thoroughly and soaking it down with CLP. I then loaded my mags with one round of brass case for every 9 of steel. Then, I headed to the range.

Fully expecting to get a stoppage before the end of mag number two, the AR kept eating the steel case well past that point. The brass coming out eventually carried a considerable amount of black deposit on the outside of it. It was rock hard and couldn't be scraped off with a fingernail. I did a variety of shooting, including slow firing (shooting once every 20 seconds or so), sustained slow firing (shooting once every five seconds), fast firing (shooting as fast as I could pull the trigger) and even some bump firing (near automatic rates of fire).
