Barnaul vs. Wolf Ammo

[NoGo]

I've shot only Wolf and no name import Russian ammo in my AK's, but read that Barnaul is apparently hotter. Has anyone chrono'd the speeds of the various cheap import ammo.

Never chronoed any 7.62x39, I feel it is a waste of time since it is a "suppresive fire" round and not a tak driver. I have not shot any Barnaul before, but some guys say that they get tigher groups with Barnaul than Wolf.
