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

Ohhhh, A puncture. This makes much more sense now.
I once had some Rem primers do that in my bolt action back in the day with some hot loads.
I'll pay more attention to my CJ95, I noticed odd smoke as described coming out my 16" the other day, but the machine kept running and I thought nothing of it. So far my 11.5" has eaten it up no problems.
I went through almost a case in three different AR's without any problem then in a carbine course near the end of the day it jammed up, so I went to my Tavor to finish the course. The other day at the range do a couple of rapid fire drills again it jams up, after I finally clear it, low and behold there is the culprit a primer in the locking lugs. Try the same thing in my other AR jams again another primer. My buddy is shooting his AR it jams there is that primer. I'm thinking heat might also bye playing a role in this. Winter and spring no issues. Issues started in the summer and when running the gun a little hard. Mine is CJ93. So I've personally seen the same issue in 4 AR's ranging from 14.5" to 7.5", plus basically the guy I was shooting with had the same issue in his and he was the one to tell me what to look for. I'm also sure they were full primers that were blown out. Maybe I'll save it for my cold weather ammo.
PS the makes of the rifles also varied so I can't see it being rifle related.

I originally had problems extracting when i first bought the rifle over a year ago.. i installed the extractor booster kit from brownells a few weeks later and not a single hiccup since then, until i started using this ammo a few weeks ago.. but i never had extraction problems with it.. just the bits of primer in the bolt causing misfires and stuck bolt syndrome.
i dont know if i mentioned before, but i had put a couple of hundred rounds of the norc ammo through the rifle before i started having problems.. it was a second batch that i had bought that started giving me problems.
Im shootin a 14.5"
If you look at the pic i posted on the first page, the primer is still there, but there is a significant puncture in it. the chunk that got spat out the back is ending up in the BCU. In my case, i have found them mashed in the firing pin hole.

Anyone with a 20" AR that is having problems with this ammo? I have spam can on the way.
No body here wants this stuff to work more than I do..... I priced out some other options, and their all pretty expensive. I considered going to steel, but I want the brass incase I decide to reload in the future!
It has been explained to me that after a number of breached primers, the hot gas that blasts past your firing pin can actually sharpen your firing pin. This makes it even more likely to caus a problem going forward. I'm beginning to wonder if the same gas has deformed any part of my bolt.

I have ran the CJ95 in multiple ARs , Tavor and Swiss Arms , the primers pop out and jam up the action, It short strokes in the Tavor for some reason ? , the Swiss runs it fine it seems, i think it just chews up the primers with that beast of a action lol ? With my ARs i cant even get through 100 rounds without having to pry a primer out of the locking lugs ,I think DI rifles make the issue worse for some reason ..
When i reloaded some of the brass the primer pocket did seem less tight than most when i seated my new cci primers , i shot 50 reloads without losing a primer .. so the chinese primers could be a bit undersized .. They should have crimped the primer pocket, its a shame, because this ammo otherwise is clean burning and accurate. Hope they never sold it to anyone who had their life on the line! This ammo would be a absolute nightmare in a select fire rifle or LMG.

i havent had any problems in my 20 inch AR yet.. only my 10.5" and my buddy's 14.5".. i think this weekend i"ll take it out and put 40 or 50 rounds through the 20" and see what happens.
That's what I was asking myself...
I received my crate yesterday, I hope my lot is a good one... I should try it next week.
Lot # 31 made in december 95
