I broke out my chrony the other day and shot a few mags through:

Nork AR with a 20" bbl
T97 (I think with a 18.6" bbl)
Nork AR with a 14.5" bbl

Going off memory (my notes are in the car)

With the 20" bbl AR, I was getting in excess of 3400 FPS.
With the T97, I was getting 3300 FPS
With the 14.5" bbl AR, I was getting 3150 FPS.

Hot stuff...

Is that so ?

Those number do not seem too far from federal M193 ball ammo:

Still looks a good 100-150 FPS faster than Federal M193... let me go grab my notes.

As for accuracy - shooting unsupported from a bench, the best 5 round group I could get was about 5" with a Vortex PST at 4x magnification at 94 yards with the 20"bbl.

My optics for the other guns were an Eotech 512 on the CQ and a Vortex Sparc Gen 1 on the T97. My eye is still screwed up after my surgery and I could barely make out the target, but I was averaging 4/5 rounds on paper (8.5x11 CanAm targets) at 94 yards - but I was making 6-7" groups, even off the paper.

Not stellar shooting - but hopefully when my eye's heal and I can see what I'm shooting at, I can actually do a little better.

I had heard something along those lines, that because they're NATO specs they're fairly hot compared to M193. Made me want to save them and shoot the AE223 (XM193) cheap stuff until that runs out. Initially I wanted to shoot older ammo first. Ballistics were all over the place though, it's not easy to get a good group from surplus. They tend to pattern in a way that makes you wonder if you could sort them first you could get great groups! Shoot 100 and you have 4 or 5 nice groups patterning, and a bunch of fliers in between.

Doesn't appear to be any hotter in my Stevens 200 coyote gun in .223. It was sighted in over 3 yrs ago using Remington UMC (55 grn) as that was what I had on hand at the time. Tried out the Norc ammo today in the same gun, instead of my DPMS precisely for the "internet warnings"....ho hum. Same POI in my bolt gun. Is the "concern" over it being hotter unfounded or did I get shorted a significant amount of FPS in my batch (Dec 1995 mfg)?

For the sake of clarity, does Norinco actually make 223, or are you talking the mil-spec 5.56?

I'm more just curious to see if they make a 223.

All norc ammo is made for military use, so it's technically "5.56 NATO."

Yeah - I suspect if not for the tens of thousands of rounds some people :rolleyes: keep squirreled away in their basement furnace rooms, most of it would be in the hands of the Taliban, ISIS, or Russia - so you army guys can thank us civvies with more money than brains for depriving the "enemy" of a highly valuable commodity.

After all - I'm sure those bad guys wouldn't mind getting crates of this ammo, along with crates of $600 Chinese made AR15's.[/troll]

Oddly enough - some guys I shoot 3-gun with are a bit concerned by the stuff so as to not let guys shoot their AR-500 steel with it. Some suspect it might dimple the steel (as of yet to be proven - but seems possible).

There have been some sporadic reports of Norc 223 sticking to magnets, suggesting that occasionally some lovely bi-metal bullets get tossed into the mix. There was the one lucky so-and-so that opened his crate of 223 and found 308AP, it can be hard to know what you're getting until you gets it.

Out of the big sale a few months ago (I bought two crates), I have not had a single Noronco-fault stoppage.

At first I started having some with my Mossberg MVP, but on closer inspection the primers were less and less struck, until finally I realized the firing pin was jammed. Fixed for free under warranty, and since then my MVP and DD M4A1 have fired hundreds of trouble-free Norinco 5.56. It may not be target match accurate, but it is well within the margin of error of my accuracy when I'm going for "just okay" speed vice precision. I'm getting everything inside a square foot on rapid rate with a red dot, so I'm happy.

Yup lots of people shoot it trouble free, and there have been zero actual problems, such as being overcharged with powder. The reports of keyholes, loose primers that make their way into the trigger group, and in my experience blown shoulders really are minor in the grand scheme. No one has any evidence of it wearing barrels faster, and with our mag cap laws it's unlikely that it's noticeable. The majority (I assume) are shooting it through an AR, so the barrel change is pretty easy anyway.

Saw posts from one guy who bought a full crate of 7.62x39. When he opened it up he found out the whole thing was full to the brim with tracer rounds.

But you gotta be a lucky SOB or buy a lot of ammo before that works I think.

Hmm... it's like blind bag toys for grown men.

Sometimes you get tens of thousands of the exact same "common" toys.

Once in a while you get the rare sparkly ones.
