It is the first time I see this and I wonder what is wrong with my gun. Yesterday after shooting I collected my .45 brass and notice that a few of the fifty brass were damaged.

The damaged ones looked like someone put them up and smack them with a little axe shaping a big «V» in the head of the case. Don't know if you understand but I will try to post a picture if no one know this problem.

The ammo were Remington UMC 230gr FMJ (white and green box) and the gun have a rounds count of about 150 shots and was purchased new this winter. I had only one malfunction with the fifty rounds and found after the shooting session that at least three brass were damaged.

Any info?
Thanks.
 
"The damaged ones looked like someone put them up and smack them with a little axe shaping a big «V» in the head of the case."

VZsammy, the V in the head of the fired cases is not reserved for Norincos and it is not uncommon. I have reloaded tons of brass that was altered by a V and it is fine unless the rim collapses during resizing. Regards, Richard:D
 
My NP30 does the same thing with the Remington UMC but nothing else. I figgure that it is from the brass not ejecting far enough and the slide slams shut on the brass as it is 1/2 out of the ejector port. Funny tho it only does this with the Remington UMC 230gr (.45acp) and not the factory American Eagle. I have yet to try other ammo.
 
While I've never had any problems with my norc I do have problems with UMC brass.

I've found with 45acp it is much softer than federal or winchester brass. Even to the point where I have toubles reloading it after two firings as the cases buckle under the slightest pressure.

Maybe the softer brass causes this mark to be more noticeable.
 
"...slide slams shut on the brass..." That'd cause the pistol to jam. The 'V' is caused by the brass hitting the pistol on the way out. When start reloading(You will sooner or later. Shooting factory gets expensive), the expander in the sizer die will fix it. It's not a problem with the pistol though.
 
I have shot the same gun and Remington ammo and it happened again today but this time the gun jammed on the last round allowing me to see the problem.

The notch is VERY BIG(read spectacular) and there is no way the brass could be shot again unless reloading involves some plier actions...

So here it is, the ejection port closes on the brass making a big "V" notch but ejects it anyway. Only one time did the gun failed to eject, as the mag was empty the brass was pushed back in the mag and the action was stuck that way: Head of the brass forming a "V" around the front of the ejection port and the bottom was stuck in the lips of the mag.

So what do I do from there?
- Is it the ammo like someone suggest?
- Is the the new Mecgar mag?
- Do I contact Marstar for waranty?
- Do I contact Armco and have them to work on it?(I found the trigger to hard anyway and the sights aim to high)?

Thank you very much everyone.
 
Pretty easy to determine if it's the mag if you've got others to try.
Could be your extractor needs a tweak or your ejector needs some tuning...
Does your Norinco allready have the lowered and flared ejection port?
 
could this be related to a slightly heavy recoil spring for the ammo mentioned?
this may cause the slide to not go fully back and cause a "short stroke" which though it ejects the spent casing, causes the recoil/lockup stroke and timing to be shorter. My buddy had a norc pistol that kept catching the spent casing sideways, jamming the gun. A lighter recoil spring solved the problem. I do not remember there being any case damage though and he was shooting fiochi 230 gr ball
 
My money would be on tuning/tweaking the extractor and ejector.

the relationship between these parts and their interaction with the fired/ejecting case, in large part determines how the case exits the gun.
Usually the V dent in the case mouth (the part where the bullet was located) is caused by the case striking the lower edge of the ejection port.

that can be adjusted by judicious filing of the ejector to change it's point of impact on the case head (the part where the primer is located) to clear the ejector port edge, eliminating the dreaded V dent.

Sometimes in finicky pistols, the variation in case head dimensions between various brands can make a real difference in the consistency of the ejection pattern.

Gunnar at Armco can do wonders with that, and give you a sweet trigger too.

2 cents Eh!

If you allow your wrists to be somewhat loose while your shooting can cause this problem. If you dont have a firm grip and try to keep that muzzle from flipping, what happens is your wrists actually absorb some of the recoil and will cause cycling problems. I wouldn't do anything to the pistol apart from shooting it more. Just make sure you grip that sucker tightly and concentrate on trying to keep the gun straight without allowing it to move from the recoil. After the the gun has been fired lots, the recoil spring will have broken in a little and that will help as well. You can make almost any auto malfunction that way on purpose by shooting it leaving your wrists completly limp. As a matter of fact, i think there as even a ruling change in some competion about that. Some people where causing a Fail to eject on purpose when they were having a bad round and that would allow them to re-do the round. When people found out that this was happening, they changed the rules. Im not 100% sure what form of competition it was in, whether it was IPSC or something else. But I know some people were abusing that on purpose in some form of competition.

Anyways, im almost postive that this is what's going on. If there was something wrong with your mag, ejector or anything else for that matter, the problem would happen alot more often.

My 2 cents anyway :redface:

Cheers,

damaged brass

I had this happen on my Norinco as well. It was caused by the extractor tension being too weak. This causes the spent shell to be dropped by the extractor part way through the extraction. If there are still rounds in the magazine it is no big deal as the next round prevents the spent shell from tavelling downwards, it strikes the ejector and all is well. The problem is with the last round, as the shell is dropped by the weak extractor, it falls down toward the magazine. It doesn't strike the ejector properly and is therefore still in the ejection port area as the slide starts traveling forward. This smashes the front of the brass as the moving slide causes the brass to strike the barrel edge, then it is thrown clear.
 
This thread is ancient , but the best I found in search about a problem.
My issue is with a slightly used , new to me , Norinco , using Fiocchi 230 gr. fmj ammo . First night out , things ran fine for about 30 rounds, spent cases ejected to the wall about 4 meters away. Second time out , I had a jam after about 20 rounds , third round from the mag. Norinco mag the first night , Italian mag the 2nd time.

Empty brass stuck half way out of the chamber , extractor hooked on very well , and could not manipulate the slide open or closed. With some MacGyvering , was able to apply enough force at the front of the slide to bang it open and brass ejected ok.

Inspection of several spent cases shows some breech face marks on the head as well as a very solid primer strike with some cratering , which makes me think over pressure ? Factory loads

After the first jamb , stripped the gun down , everything looked proper and was clean and lubed well . Extractor hook was fine , firing pin smooth and round , pin hole ? in breech face looked ok , circular and no chamferring.
Barrel and chamber appear clean , spent brass drops in to proper depth . Not sure that I tried this with the one that jammed or another.
Reassembled , and stroked some rounds through from mag , all seemed ok. Fired 9 more and jammed again , same way . Parked it .

Thinking things through , not sure if I have more than one issue .
If extractor is too tight , can it not release the empty and then try to stroke it back into the chamber ? Off center enough so that it jams hard ?
Stiff spring and light load maybe would cause weak stroke , but marks on brass show this is not a weak load. Spring seems comparable to another from a Colt that was available for comparison of parts.
Are Fiocchi primers so soft as to flow into breech and firing pin hole ? Marks on brass face from Chino machining ?

Plan is to try another factory load , with both makes of mags , and some serious stiff wrist shots . Thinking how limp-wristing may effect ejection and pressure causing marks on brass , two issues.
Any other ideas out there ?
 
That factory Fiocchi sh1t has blown some guns to splinters (over charges from the factory !)

Have found nothing negative in all CGN threads except some feed issues , some new problems maybe ?
maybe anew thread is in order. The marks I am getting seems to point to pressure for sure.
 
I'm with 45ACPKING the recoil spring is too heavy and the slide is coming forward before the spent brass clears the ejection port. It is easy to swap the spring. Try it and see. Are you running a recoil buffer? That could also be contributing to the problem.
 
Why are you yelling, and the case was pressure expanded (stuck) in the chamber. The primer burned (flowed) into the breech face. All indicators of over psi.

Check the black powder and antiques thread for known Fiocchi ammo problems (over pressured factory rounds, squibbed rounds), you name it. The stuff is sh1t. QC issues abound.
 
Fiocchi is loaded on the high side of CIP (European) Specs - generally CIP specs are higher than SAAMI (US) specs due to the lower incidents of liability suits in Europe. S&B 45 is hotter than US commercial ammo too.
