There was a long discussion about the above a year or so ago.Something about the steel case ammo being hard on extractors. Can't find it with search mode. Could I get some help. Was there a difference in the ammo in the 1000 rd cases vs. the 1040 rd cases? Thanks!

Only difference I saw between the two was one came in 20 round green boxes and the other was approx 125 rounds wrapped in paper in spam cans(4 of these per can). Any steel cased ammo will be harder on extractors and such over brass cased. Personally, my Dad, Brother and I have shot a bunch of this ammo in our rifles and it seems good. It chronographs on the higher end of NATO spec velocity while the Czech surplus we have is on the lower end. The Norc IIRC, is about 2700-2750fps while the Czech is between 2600-2650 fps. Our rifles seems to shoot it quite accurately, YMMV of course, but we are averaging around 2-2.5 inches at 100 yards.

Also both the Norc and the Czech ammo is berdan primed so we treat it as corrosive, just in case.

I think they are, when I disasembled my gas port in my m305 I found some surface rust a weeks after the shoot. Nothing nowhere else because I cleaned it, just forgot the gas port.

Good to know. I've never had that problem as I've always tried to be diligent with cleaning my 2 M305s.


IIRC you should avoid the laqured ones, copper wash ones should be gtg

I've never seen or heard of lacquered 308 ammo. Learned something new today:dancingbanana:
 
I've shot a few thousand rounds of the Norinco crates and never saw any evidence of rust. I've never even had a FTF ever.
 
I'm not sure about the Norinco ammo being hard on extractors, but my M14 eats up that ammo. Never had any issues with the ammo, but I'm only a few hundred rounds into my crate.
 
I've heard of issues with certain brands of steel cased 223/5.56 breaking extractors in AR's but that's it.
Only complaint I've read about Norinco 308 in Norinco M14/M1A's is the copper wash coming off and leaving copper residue in the chamber. It doesn't effect the function of the rifle but some people don't like the look of it. Normal solvents don't clean it up well but copper dissolving bore cleaners work great.
