who cares if ammo is dirty, that's why we clean. I've never seen, heard or even heard a rumor of anyone "blowing up their gun" with norinco ammo. I've also never seen a 1911 that wouldn't cycle it reliably...well i have, but 1) is was an expensive north american made brand new gun starting with the letter "C", and 2) that pistol would not cycle ANY ammo at all reliably, and was returned for refund.
I've only known one or two shooters who can shoot more accurate then the norc ammo is capable of, and then they can only do so with full on deliberate bullseye shooting, Once they switch to IDPA/IPSC they might as well shoot the norc ammo...
If you don't like cheap chinese ammo, just don't buy it, but no reason to pretend it's much worse then anything else...it's not. And it contains/releases no more lead then any other type of ammo unless you shoot lead free primed Win-Clean ammo all the time.
Suprised that no one commented on the fact that Wilson Combat thought Norc frames where good enough to build customs on when they where available in america. Jerry Kuenhausen also commented in his books how good their frames where for platform builds, compared to what was available in america.
