I've had no issues with 'basic' performance on those that I have shot, but I've only shot maybe 210 rounds so far, so I can't provide a full report.
I've resorted to simply putting them aside and focusing on other stuff.
I scrounged a considerable amount of Remington nickel plated brass that day as well. I guess I have several hundred at this time.
I have since learned that this was issue ammo for a couple of our 'range guests' at work, and the next time they visit, I'll be looking for more!
If nothing else, they'll be nice to reload - put on stripper clips - and set aside for a 'rainy day'... ;D
