I was shooting my baby recently, and this occurred only once, but it worries me. There was a light strike on the primer and the casing was severely damaged and the bullet was loose and on a funny angle....

I am unsure if the bolt was completely closed but I am pretty sure if this baby went off I wouldn't be a happy camper...

Anyone have any ideas on what would cause this and how to fix it? I kept shooting afterwards and she was fine. The round was perfectly fine when loaded and came out this way so it has me a tad worried..

Thanks for any help you m14 nuts can provide!

Might have stove piped on ya.
Off the top of my head I'd say either a short stroke or check the mag lips on the front end on the mag you had in when it happened.
Type of ammo?
 
That appears to be an MFS 145g from the looks, but I could be seeing things funny because I was just playing with a strobe light.

Funny how yoga studios get all pissy when you play with your strobe light during one of their stretchy sessions. My office is directly across from one of the bigger ones here in Victoria, and I just got a new flashlight that says "Tactical Special Edition" on it, and it has strobe light functionality.

Some of those yoga girls are pretty hot tbh, but then sometimes you get those old granola looking grannies come walking out of there smelling like pickles. Not that I make it a habit to smell old people, but you know how it is.

I am actually unsure, it came with the gun when I bought it and has no labels on it :S

I just cant leave all that ammo alone and unshot....

so it is definitely surplus steel cased.

but since the primer is struck, I cant see how it was a short stroke or a stove pipe... it was in the chamber when I extracted it, I just cant remember if the bolt was completely closed or not. It must have been since the primer was struck... I took it apart and cleaned it after and the bolt looked like it had a gentle curve in it, but I am unsure if that is normal or not since I am an M14 newby.

anyways, I will be very cautious when I shoot it from now on regardless in case it blows up in my face.
 
I've had this happen to me with reloads, where the round chambers but pulling the trigger just lightly strikes the primer. This only ever happened when I was using a powder deemed too slow for the bullet weight I was using. This never happened on the first shot, only the 2nd or 3rd. I switched down from 165g to 150g and the problem went away. I have the same issue when I follow the bolt handle forward on charging, I believe it doesn't give the bolt enough force to actually clip onto the rim.

It may be the timing on the gun, or the ammo sucks. I'd get it looked at, because an out of battery firing could result in bad times for you.

I agree. too bad no gunsmiths in calgary will go anywhere near a norinco M14... Plus half of them are a$$holes in calgary anyways.
 
Have you checked to see that your gas piston bolt is screwed on tightly? That's the thing that regulates the timing. It's supposed to be finger tight plus 1/8th turn with the wrench, that's what a gunsmith told me.

If it's too loose, the piston won't be sticking out enough.

If you're rich, I'd just send the thing to the doctor and have him determine whether the gun is worth dumping money into. You could also just wing it and try other ammo, it could be that simple. Personally I would just use a string to pull the trigger and fire off a bunch of rounds from behind a wall while the gun is in a vice with the federal blue box stuff before I jumped to conclusions.
 
yea, I have put near a hundred rounds out of this thing with no problems except for this one. It may have been the new magazine I was using (5/30) but it could have been many other things.
 
For what it's worth, 90 INCH pounds is what my gas plugs are tightened to. However I don't think the timing would be the issue. You mention an aftermarket 5/30 and these I've seen and don't use as I found them problematic.
A mis-shaped or slightly bent magazine lip can cause the nose of the round to miss the chamber opening and make contact with the barrel where it shouldn't. Obvious damage to the round would be the result.
Also if a mag is not fully seated a similar result can occur.
Just throwing out ideas
 
Dirty gun ?

I'm not sure if this is a fair comparison, but this happens regularly with our AR-15's. It usually can be attributed to a very dirty gun or putting slight pressure on the mag while firing. Just enough to change the feeding angle. You brought up an interesting point that I must check at the range. AR-15's have a floating firing pin which will dimple the primer every time you chamber a round. Now I gotta go see if the M-14 will do the same thing. Obviously, it would not be advisable to rack a live round in the house.
