WOW-- THis is what I call a Weapon Failure!

I don't know how the shooter wasn't injured beyond what he received. Nice analysis by Fulton Armory though.

But with all the damage he got lucky it wasn't worst. I had a HK G3 blow up with a wolf ammo a few years ago and it actually did better then the M1a. But it was toast. Got alot of the parts off it and cut the reciever so know one could get hurt.

whew! no more cheap stuff for me

Lose the s. African ammo!!!!:d:

Read the report from FA, the failure wasn't the result of the ammo it was improper heat treating of the steel.

If I had not seen the pictures I would not have believed that this could happen with this design. This is the kind of plastic deformation you see when the pressure pulse is applied in microseconds (detonation) instead of miliseconds (combustion).

I am having a hard time seeing how the heat treatment of the barrel, the receiver, or the bolt could have caused this. Perhaps you can post the additional details.

Sure, I parsed through it a bit (it was a bit hard to read as it is all in science jumbo I will post what I think it is saying ).

"An examination was made of a failed M14 rifle. The receiver was identified as "U.S. Rifle, 7.62-mm M1A, Springfield Armory, Serial No. 03055." The receiver was split into two pieces. Failure was at the chamber end and initiated in the threaded region.

There were no indications of excessive pressure in the case that would have contributed to the cause of failure.

In summary, the failure of the M-14 barrel was the result of a poorly formed microstructure in the steel."

These are the high-lights. They did a highly detailed, like xrays and such, which showed too much ferrite in the steel that should have been minimized if the steel had been treated properly.

THe guys weren't sure who made the barrel as it wasn't a marked USGI barrel.

I guys the barrel's steel gave up and fractured in half which caused the receiver to split in two as well. THe shooter is lucky that it split left to right and not up and down.

Fulton has been bashing Springfield on the internet for years...Those receivers are made in batches, they're not heat treated one at a time, if there was a problem with heat treat, there would be ALOT more failures.

I try and buy good ammo no forien stuff

It wasn't the receiver that failed... It is the barrel that failed and it was not a standard USGI barrel...

I give-up I don't know why I bother trying any more...

So what you are trying to say is that PTR is not the only company with defective barrels?

I'll be darned....never seen anything like it....just when you thought you've seen it all.

lmao, apparently... I guess the lesson is to make sure you give your rifles a good once over after taking them to the range.

In defense they said that the rifle had the appearance of being used and abused so they was probably quite a few thousand of rounds through it.

Thanks for the added details. Too much ferrite means that the carbon in the steel was not fully dispersed through the grain of the material. Just think of shooting a barrel made from cast iron and you will get the idea. Fracture origin in the barrel threads is also a give away. Who ever produced that barrel should be hung up by the gonads.

Sheet that get my attention

[Brew]

I kid you not.....when I shot the chrome layer out of that sks, it was a real wake up call. the entire chrome liner pulled free and went out with the bullet and though the barrel didn't rupture it was a deafening explosive sound. I saw a two foot flash that looked like a lightening bolt go a hundred yards and knew that rifle was done.

[MikeK]

That would be a big part of why I handload. Better quality than premium factory ammo, costs about the same as surplus, and if you're a good reloader, no worries about kabooms.

[NCDoberman]

Holy crap look at that barrel.

WOW! that's one lucky SOB.

yikes,quaity pays in the end
