has anyone had problems with the Norinco 223 ammo? its the stuff that comes in the "sardine can" box.. i've shot federal, IVI and all other types of ammo without problems..

what happens is i"ll shoot off 5 or 6 rounds then i start getting misfires... the primer is not hit when this happens.. eventually my bolt will get stuck and not open and i have a hell of a time getting the live round out of the chamber..

when i get it out and clean it, i get this metal stuff that looks like chunks of brass falling out of the bolt.. (see pic.. the five little pieces on the right of the cartridge)

I think the chunks of metal are getting in front of the bolt face and preventing the bolt form completely closing and causing the misfires, also i think the metal chunks are getting caught between the lugs and causing the bolt to get stuck..

this norc ammo also smokes like a bastard.. when i use it, my ar smokes from the ejection, and the bottom of the mag.. i know its not caused from too much lube in the bolt because i can shoot off federal ammo immediately after and there's no smoke at all..


i know of one other AR (also a Norc) with the exact same problem..

again, all other ammo works great..

has anyone else had problems with this ammo?

 
those are primers popping out that's why your getting so much smoke. I find it strange you are getting so many in a row i would check the rifle for any issues then try the ammo in another rifle
 
Try it in a non-Norinco AR if you can. The Norinco ammo seems to vary a fair bit by the case lot and it acts differently in different rifles.

I had a case last year that was terrible in my ARs. Blown primers, signs of excess pressure, etc. It worked flawlessly in Norinco ARs. My latest case of Chinese 5.56 works flawlessly in my ARs, yet exhibits pierced primers in my buddy's Norc AR.
 
Yes we have had lots of problems with it. The little pieces are from the primers, if you check them you will see holes where the firing pin struck. These pieces get into your bolt head and jam up the firing pin. Also the gas that escapes causes a fair amount of erosion.

Wow, I'm seriously not impressed! I guess the old adage still holds true, you get what you pay for...

I can go one step further.... i was getting a lot of issues with this stuff as well, so much so that i think it may have broken my firing pin!! those little pieces were all over the inside of my BCU. The last time i went to the range, i got 10-15 rounds in, and it jammed up SUPER tight. Once i pulled everything apart, i found my pin had snapped!!
The problem is, i have had the same thing happen with other ammo as well.... I was starting to think that my AR was defective, however maybe there was leftover crap still in the BCU...... im guessing its the ammo after all?

note the busted firing pin,

and the bent retaining pin.

These fell out when the extractor was removed....

Have a look at some of your fired brass and you can see where the little pieces are coming from

What's the headstamp on the spam can ammo? I have several of the 1600rd cases in yellow boxes - CJ 93 - and have no problems in my AR and 2 Mini-14's.

Is the spam can stuff a different year?
 
Head stamp is C J 95 on the problem stuff..

I'm having this problem in a Norinco CQA with a 10.5 inch barrel.. One of my buddies is having the same problem in his Norc 14.5 inch AR (including the bits of metal)..

I checked my fired brass and didnt see anything strange on the primer.. it looked like a normal strike.. unless its the anvil from the primer thats getting lodged in there..

i never found anything in the trigger assy area..

I shot the same amount of rounds (about 20) out of my Colt HBAR 20.5 inch barrel and didn't experience any problems with it..

The strange thing is that this problem just started recently.. i had previously put at least 200 rounds of this ammo through the CQA without any problems.. maybe a different lot or something.. very strange

ya the stamp on the one in my pic above is a CJ 95 as well. I started collecting my brass about a month ago, and i didnt see anything odd about any of it. lately however it seems about 1 in 10 has a little chunk missing from the primer, right where the pin hits it. Im running it through my NEA-15 if that matters. Im hoping the warrenty might kick in and replace the firing pin for me....
 
i know people that have shot many thousands of this ammo without issue (tavor/ar/vz58 ) myself included. Either this is indeed a bad batch or the rifles having issues are out of spec in some way

whats the barrel lenghth of your AR?
 
Every time i shoot this norinco crap it pops primers out and jams up my guns , i will get primers mashed up in the locking lugs and trigger group so bad i have to pry them out with a screwdriver . My Tavor short strokes often with this ammo too , its pretty accurate but not worth the other issues i wont buy anymore cj95

We have had the problem with AKs, SG540, Norinco and DPMS ARs, and several other rifles used by customers. It appears intermittently and in my opinion is not a result of high pressure but rather brittle primer material. Perhaps specific lots of primers.
 
I still don't understand how a primer can be liberated from the case when it is being held in by bolt face. That is, unless your AR was very very poorly timed.

Any primer would pop out of any caliber if it is not properly supported, there has to be something more to this.

I'm only about a few hundred into my case of CJ-95. So far no problems other then a couple of fails to extract with my 16", but that's a gun issue I'm aware of.
My last case of CJ-93 rocked.
 
there is a reason this is surplus.
Im on my 7th case on cj 95 and we have had about 400 rds that have been an issue mostly the shoulder not correct and jamming.
we dod do an event where we put 1000 rds down range on a high standard 20 inch h bar ar15 we have over 300rds in that crate that did course jams
most of the issues I have seen are tumbleing.

The primer is not poping out. The firing pin indents the primer. The small indentation is then blown into the firing pin hole of the bolt.
 
Shot over 400 rounds of CJ95 thru my ACR not a single hiccup and accurate enough to hit a 16x28 gong as many times in a row as you want at 400 yards. The ammo has run perfect. No signs of any sort of issues
