Anyone chrony Norinco 5.56mm yet?

[The Baron]

I tried searching and couldn't find any information on actual velocity of the Norc "spam can" 5.56 ammo. I'm curious if this ammo is under powered, average or "hot". Anyone have velocity data on this stuff?

 

[little_airwolf]

I asked if anyone had stats on the Norinco ammo. Nothing.
I have a Ballistics program and would like to know the BC of the ammo.
Hope someone replys to you!

I've got a chrony, so if nobody had data I'll get that for the group. I'm just being lazy and trying not to duplicate the effort.

If I do it, I'll chrony Norinco, MFS and whatever other ammo I can drum up from the "budget minded shooter" pile.

i recall in one of the NEA fail threads, where a bolt blew apart, dmcfaul blamed it on the norinco ammo used. said it was too hot IIRC

just had a look for it, but it is gone now.

It does about 3150 out an 18" AR. It's got quite a big spread as well but for what it is it doesn't bother me.

Out of a 20" spout, that stuff would be right where it needs to be to qualify as 5.56 NATO would it not?

It's often touted as M193 spec ammunition so I'd imagine that is the case.

Shot lots out of various mini-14s years ago and compared to other commercial,military and suplus ammo I would say it was realatively hot.thanks--Dieseldog!

All were 10 shots over the crony 20' from the muzzle of an 18.5" tavor.

Norinco white box 3209fps ES 110

Norinco red box 3143fps ES 60

Norinco yellow box. 3213fps ES 74

AE 55gr FMJ 2931fps ES 106

MFS 55gr FMJ 2910fps ES 172

MFS 55gr HP 2890fps ES 102

Hope it helps.......

Good information thanks

 

[Antoine22]

It's actually hotter than I expected. Thanks for the info.

 

[saskcop]

That stuff is sure moving! Need to buy another case.

Just bought some yellow box Norc from SFRC. These will be my first Norc ammo so if anyone can tell me what's the quality like it is brass cased but are they accurate for the type of ammo they are or not.

Thanks

I would expect 7" at 100y.

Anymore and it's gravy!

It is currently the cheapest 223/556 ammo out there by a fair margin, made in china with the loosest possible spec.

But then again, I've never had North American made plinking ammo under 5" either......

Ymmv!

Thanks just was wondering what to expect

If the warm weather would just get going i would love to crono some Norinco as well as others, how long does 5' of snow take to melt? I'm starting to get cabin fever and need to shoot some gophers. So far i have seen minute of manchurian elm with norinco ammo, missed the magpie.

It really depends on which rifle you're shooting it out of.

The primers are hard as all get out and if your rifle doesn't have a strong enough fireing pin spring or striker spring, you will get misfires and inconsistent ignition.

I have a CZ527, that shoots the Norinco into sub 1/2 groups at 100 yards.

I have pulled the bullets and they all weigh within .2 grains of each other. The powder charge is 26.8 grains plus or minus a two tenths of a grain, of ball powder.

I also drove out the primers and replaced them with CCI small rifle magnum primers. My Tikka T3, Remington Mod 7 and Marlin XCR put 10 rounds into ragged sub .75in holes.

I will admit, those primers are a real issue. If you don't mind pulling all of the bullets and reweighing the powder/replacing the primers, it is very good stuff.

It works fine in my 1977 dated Mini 14. Goes bang every time and shoots into 2 1/2 inches at 100 yards. Good for a standard Mini 14.

The real caveat with this Norinco ammo is the primers. It really needs a hard, solid whack to get consistent ignition and therefore decent accuracy. Of my bolt actions, the only rifle that gives me reliable and consitent primer strikes is my CZ257. A friend has a Rem 700 that has a heavy spring as well and it shoots nice tight little groups as well.

Some Mini 14s don't seem to have enough spring tension behind the hammer to strike the primers hard enough either.

bearhunter, do most AR-15 rifles have sufficient firing pin force do you think? new to the game and want to have all the info I can gather.
