I find the Russian ammo in general accurate and reliable. Great plinking stuff at bargain prices.
Most problem I know of with Russian ammo has to do with extraction systems that do not like steel cases.
I have fired some of the Wolf steel cased 308 ammo thru a Rem 700 heavy barred match rifle despite sceptics telling me I would be lucky to keep the rounds in the black and would damage the rifle. The group was sub-MOA at 200yds and the rifle did not blow up.
I for one am greatful importers are supplying Russian ammo to us here in the USA.
