I ran across a brick of Russian made steel cased 22 lr rounds i purchased in the 90's and misplaced over the years and decided to shoot them up and not a single round would fire! I also found some old federals that were about as old and every round fired. I spent a good deal of time pulling the bullets from the Russian stuff for the melting pot and some of the powder was in cake form as it had collected moisture as bad as blackpowder and others had dry powder but the priming compound had broken apart and fallen into the case. If you have any of this ammo i would suggest that you do not attempt to keep it in storage.

I've also bought a box of "steel cased" Russian .22 LR ammo. I found that when they fired, the cases wouldn't eject from the chamber, and you needed a rod to remove the fired case. Now this was in my bolt action .22; they might not do this in semiauto .22's.

I have a case of Steel Cased Russian Jr. I haven't shot them in years but the last time I shot them, I had trouble extracting them from my Revolver. Do steel cases expand when they are shot, is that why won't eject easily?

I just found three unopened bricks of the Russian Jr. ammo. I remember buying it for something like $100 a case. It worked well in some of my guns and was problematic in others.
Gotta give it another go.

I never could get that nasty, sticky, crap to shoot reliably in any rifle or handgun, so I put the remainder of my "seagreen" brick back in the ammo locker.
