Quality control seems to have moved toward the "worse" side of things rather than the better, as far as bulk 22 LR ammo goes. Citing the example of the Winchester 290 self-loader rifle I spoke of earlier......in the late 60s through the 70s, just about any make of 22 LR ammo would run that little rifle very reliably. It has been shot quite a bit--probably 5K rounds--but it certainly isn't worn out. Nowadays, only steak & lobster ammo will run the thing--CCI Mini-Mags.
Mu conclusion, based on this limited info.......with 22 LR ammo, you DEFINITELY get what you pay for.
