I bought 500 Russian made .22 LR rounds at a gun show a couple years ago for something like $5. It was stored in a locked and sealed ammo can in my shop. I finally got around to trying it a few days ago. The first 3 rounds didn't ignite, though the firing pin strike was nice and deep. The 4th round was a squib that was nearly inaudible, but cleared the barrel (whew!). At that point I quit using it and went to some Remington .22 LR I had. All was well. The rifle functioned perfectly. So I have a question. What's the best way to get rid of this bad rimfire ammo?
