Norinco 5.56mm blown primer

[CV32]

I went through one-half of a crate (560 rounds) and visually inspected each round for obvious defects. Came up with 19 rounds that had some minor defect in the brass, but which I would probably shoot without much concern. This was before the blown primer event.

Lots of other accounts of failures with this ammo... Split cases, un-drilled flash holes, primers blowing out. Still no reports of injury or major rifle damage, but it did score the chamber of my 6920.

Thanks. Guess I should have read that thread earlier ... much earlier. Not interested in scoring my chamber for the sake of saving a few bucks.

Of course you realize that 5.56 ammo should never be fired in a .223 chamber.

.223 is OK in a 5.56 chamber, but since the 5.56 is loaded to higher pressure and longer overall length due to the longer bullet and has some freebore that the .223 chamber lacks you can expect to see cases just like the on in the OP if you do it.

This may not be your problem at all. Just making sure folks realize that there IS a difference.

Doesn't help any that some stores market it as .223 Rem. not M193 5.56 that it more closely fits. I might shoot it in a cheapo bolt action but would not shoot any out of a higher end gun like a Tavor, ACR, XCR, 6920 ect ect. Don't trust the QC enough.

Yeah, that wouldn't be the issue here.
