Russian ammo made at the Barnaul Plant is good-to-go in most all quality made ARs. Barnaul Plant ammo would be your 'Bear Ammo' and the New WPA Ammo (Wolf...but NOT the Black Box Wolf or the original "Military Classic" Wolf) as well as Monarch sold at Academy, and Barnaul branded of course.

The Tula plant made ammo...not so much. That's mainly TulAmmo, and the old/original Wolf stuff.

Some here would be advised to visit AR15.com and the ammo specific section for ARs. LOTS of accurate info and real facts found there.

I had Silver Bear hang up in my chamber as well. But, when I did this test, I was using Tula (well, it was Herter’s from Cabelas, but if you read the box, it is Tula).

Before I mixed in the brass, I couldn’t get 50 rounds through the gun without a stoppage that required tools to fix.

I think there’s a lot of variation from gun to gun, esp. considering that many “homemade” AR’s are pieced together from parts originating from many different sources and it is hard to tell what parts have what effects on the feeding/firing/extracting process. It’s good to have a resource like AR15.com to use as a starting point for your own experimentation to see what works best in your gun.

Anything that gives me a reason to shoot more is a good thing.
