The funny thing about the Russian junk, is that it'll often perform best for many of the "AR snobs" who own higher end setups with M16 BCGs...and they're the ones (due no doubt to their investment) who are often most opposed to using it.
To some degree, I am one of those snobs. My guns will handle it really well, and when there's a deal on it I'll jump all over the Silver Bear 62gr JHPs or JSPs. That's the only Russian make I like in my ARs. I've found them to be really accurate rounds that I feel could be implemented successfully in a variety of applications. They're decent for target shooting, plinking, and could be equally effective as hunting or defensive choices.
But I very rarely shoot them. I just add to the stockpile when I happen to find them at the right price. I keep an AR rifle bag put together with my two go-to rifles and about 10 loaded mags...some 55gr FMJ, 62gr pen, 69&75gr BTHPs...and yes, a mag or two loaded with the Silver Bears...because I believe its a really versatile option. Kinda like a Glock. I'm not convinced they're great for anything, but they are good enough at everything to keep 'em around in my opinion.
