WASR 10 - AK47 Explosion question?...?

Here are 5 photo's of my Romanian WASR-10 AK47..... AS you can see it blew up on me.... Luckily it didn't take my head off..... I had 2 gunsmiths look this rifle over to see what caused this.... I was using Hot Shot brand polymer coated 7.62x39MM ammunition.... You will note in the photo of the chamber -- That's not the chamber your looking at but a cartridge with the rear blown off leaving the side of the cartridge stuck in the chamber....

Any Opinions.... ???

Look at the rivets that are blown off the side.... Note how the explosion blew out the side of the receiver....

Keep your chambers clean boys -- These guns are no joke when they flake!

You probably left a coated round in a hot chamber, & the coating melted, 'gluing' the case in the chamber, causing an overpressure detonation, bursting round in the chamber. This has been a great danger with the laquer-coated import ammo like the Russian & Chi-com surplus as long as its' been on the market.

WARNING: For ALL shooters who use ANY of these coated-case surplus ammunitions, DO NOT leave a round in a hot chamber for just this reason, NOT EVEN TO CHANGE MAGAZINES. The coating WILL melt and cause extraction problems, at least, causing stuck cases and overpressure discharges.
ALWAYS double clean the chambers after firing these types of ammo, making sure to remove all traces of these coatings.

Case head separation is not an unknown phenomenon. The cartridge fired before the bolt was locked. Possibly cooked off from residual heat.
I wouldn't venture a guess as to why other than faulty ammo.
I have fired 4-500 rounds full auto from a BAR, and thousands from a .30 caliber machine gun and not had that happen.

Case head separation with a damaged inner receiver has nothing to do with the chamber cleanliness. If the round is chambered properly, whether it's glued into place by chamber residue or not, the bullet will still fly forward with the same exact amount of force as a normal round....it just won't extract.

This one blew without the bolt being locked which means your firing pin was protruding and struck the nearly chambered round. Without the bolt being locked in place, the head blew off the casing and you got a receiver full of crap. It's common on dirty SKS's, too. Not "dirty" per se, just not properly cleaned.

Pay attention to your bolt/carrier and firing pin from now on

I have a wasr-10, but have never used hot shot ammo...and after reading this, I think I won't use it...looks like I'll stick with the Wolf stuff, as soon as anyone gets it back in stock.

Well I guess it is called Hot Shot for a reason. And yes, I would have a healthy distrust for ths ****. I mean keeping a gun clean is one thing but have you had been using brass this never would have happened. Can the gun be fixed?
