It is non corosive crap crap crap crap crap crap.
I have never had so much trouble with ammo as I have had with this stuff. I bought a couple of boxes from Walmart to do some cheap shooting and i so regret it. It won't cycle in my 20" HBAR A3 bushmaster. It seems to be underpowered and won't cycle the carrier group far enough to pick up the next round. It leaves a scratch in the steel casing 3/4 down the side where it doesn't go back far enough.
So after that failure I tried to finish off the partial box in my 9" AR pistol. It cycles but would fail to feed, for some reason the bolt would lock back. Before I could finish the box I had a steel casing stick in the chamber. I had to pound it out with a borrowed cleaning rod. I didn't find someone with a rod until we were about to leave so my gun sat for most of the time we were there.
You could blame it on my ARs or the ammo I had picked up as a bad batch....but. On the way there we stopped and picked up some 40SW for my friend to shoot in his IMI mini desert eagle. He had just as much trouble witht the 40 as I did with the 223. It would FTF and at times when it did feed you could feel the gun hiccup as it would fail to smoothly load the next round. It also locked up twice with the bullet half way up the ramp with both the slide and the mag jammed.
The stuff is crap.
