[b]I have found that Russian ammo works well in Russian guns.[/b]
those $250 commie guns eat it all day long without a problem.
the funny thing is...silver bear and brown bear [B]IS[/b] wolf, barnaul, polyany, novosibirk and ulyhovsk ammo that has been commericially boxed.
that's right...tula cartridge works, jsc machine building plant, etc.. all russian ammo is pretty much the same, regardless of the brand name (case finishes vary according to market and bullet design per application). the "nipple" bullet is supposed to increase accuracy, and this has been reported by some users.
[b]Maybe it's your RIFLE?[/b]
check your hammer and hammer spring. you may have and investment cast hammer that is lighter than a mil-spec hammer...and your spring may be too weak to cause reliable ignition when coupled with the lighter mass of the hammer.
