NORC 223/556 ammo jamming up my Norc 10.5 inch AR

Yes, 2 or 3 at least
I already fired some .308 Hornady Match Superformance and primers popped 1/5 rounds. I talked with the Canadian distributor and they told me that it was a bad lot and they sent me free ammo boxes. I'm still buying Hornady ammunition cauz its good stuff.
I think its the same thing here, just a bad lot. I'm just curious to know whats the lot #...
Paper wrapped or white boxes ?
So far I opened the Lot 7 stuff and it is in white boxes.
Was there any specific reason you haven't brought any if the paper stuff in?
If anyone had read my post earlier in this thread, I had a firing pin snap because of this stuff.
Got everything fixed and out to the range today, and shot some federal 223 and some Norc 556. Shot all 100 of the 223 without a single busted primer... 3-4 out of every 20 of the Norc 556 had a primer bust.
I think it's the ammo!
Now I'm wondering if the stuff in paper is the problem..... Now I'm not saying I wouldn't buy any more, but I'll be getting it from CanAm so long as they can guarantee its not in the paper bundles.
Can the norinco stuff be reloaded? I read above that the primer pockets are a bit loose.... Is that a deal breaker?

Just to clarify, the OP never said he bought it from Canada Ammo.
Norinco 223 is available at multiple stores.
I don't understand this at all..... I shot 120 rounds of the Norinco stuff on Sunday and had a total of 35 busted primers. The 100 rounds of federal 223 I shot intermittently were all perfect.
Anybody in the Ottawa area up for a meet up to run some of this stuff through their AR's?
If your a member at EOSC, I'll meet you there this weekend!
I BEG of you!! Please track your brass, and let us know how they do at the range!!

FWIW I have shot about 400 rounds of the paper wrapped stuff, collected all of my brass, and haven't noticed anything unusual about the primers at all. This was during some of the hottest days we've had this summer and I was keen to see if a primer would come loose or puncture but nothing.
Just got back from the range. So far I have put about 2000 rounds of Norinco through my ACR without so much as a misfire. Today, I had 5. Not sure on the lot number, as I don't have any of the packaging left over.
The first issue was was I initially thought was a double feed. Turns out that the primer popped out and ended up inside the lugs on the chamber. It prevented the bolt on the next round from going forward into battery. Cleared that jam, but got 4 more failure-to-fires. Each one had a small dent on the primer, but they wouldn't fire even on a second pin strike. The dents didn't look like your normal hard-primer misfire. What I think happened is that another one of the primers broke off fell into the trigger assembly, preventing the hammer from completely striking the firing pin. I field stripped the rifle, but didn't see anything out of the ordinary. After re-assembling, there were no more miss-fires of any type for the rest of the day (probably about 150 more rounds).

120 rounds from 3 separate lots stamped 93, 94 and 95 through my 14.5" Nork CQ. Not one stoppage.
Bought from Can AM, TSE, and North Sylvia. 2 boxes of yellow box, 2 boxes of white box, and 1 40 round paper wrapped package.
Oddly enough the white box I bought last year, and when a friend ran it through his 10.5 NEA he had 2 popped primers his first box.

Could this issue be due to an accumulation of loose tolerances in both ammo and rifle ? A marginally oversize primer pocket or defective primer that does not effect operation in most rifles, but when combined with a rifle that has greater headspace and short dwell time due to gas port location and barrel length (and thus higher pressures at the point of extraction), creates the perfect storm. Separately the ammo and rifle are fine, but when combined the issue arises.
I was thinking this very thing last night.
There are dozens of variables specific for an individual gun, dozens for one model of gun, dozens of makes of guns, and dozens of batches of ammo.
I had a friend categorically write the Nork ammo when he read is thread. Thing is, if there are thousands of combinations, I'd rather get to the bottom of why and find out which combinations cause issue than say its all bad.
My impression is 10.5" and shorter barrelled ARs are more prone to have popped primers. It sounds like 14.5" may have problems too, but they seem more intermittent - I will try running it through my other Nork to see if it has issues, but the 3rd one I had before had no problems either.

I honestly hope this is the case! I had no problems running the Norc ammo as far as accuracy is concerned. I'm not shooting competitions, just taking friends out to try shooting. I just can't have these popped primers messing up my BCU and possibly tempering my firing pin, causing damage.
If there the paper wrapped bunch, keep track of the brass and inspect the primers. I would love to here how it goes!
