It's all I use in AK and I've never had an issue, (not one, in fact, as far as I can remember).
I've shot the .45 since they got away from the lacquer casings and again, I don't recall one bad round.
It does shoot dirty, but no worse than the Parabellum Research reloads out out Texas I got last year. It cleans up easier, for some reason, than some of the domestic brass reloads I've shot over the years. Not a chemist. Couldn't tell you why it is..
It's down in the $350 a case range. It gets me out to the range at that price. And it's as accurate at combat distances as anything else you you can buy without getting into "target" stuff..
BTW, Ammoman has AK rounds for $300 a thousand, delivered. Been a while since I've seen that. Knock another $50 off of that and it's back in the "good old days" range..
