The French stuff that I had personal experience with was headstamped "VE". U.S. Lake City stuff is good to go and is not Berdan primed. In fact I have quite a few of that LC so dated that I've loaded for years. Far as the French crap, the stuff I had was in 50 rnd boxes as I recall and was dimensionally identical to the U.S. ammo I was using......way b ack a good friend's nephew "acquired" two full pillow cases of the stuff plus emptys while stationed at Ft. Hood. That was way back in '67......the French ammo, from what I could determine was loaded with the corrosive primers due to the fact that the French were involved in several colonial endeavors in tropical areas and the corrosive priming proved more reliable.........that said, rest assured that the VE stuff is rattlesnake venom to barrel steel. Further, it is my understanding that NO U.S. carbine ammo is corrosive....other calibers tho are suspect into the mid 50's.............worth a check on the CMP forum if you are interested.
I almost lost a 3/44 M1A1 bbl to that crap........caught it in time and dumped the ammo in a salt marsh. No experience with the ChiCom LC, but have heard its a no go.
Load your own, cheaper and a lot more satisfaction shootin' cast anyway. I get 100% function with 120 cast using 2400......both full and semi auto.
