Reportedly occurred in the Honduras.
Round failed to fire. The shooter pulled the bolt to the rear and the round cooked off. Ammo was dated from '82. No additional info at this time. Poor Barrett..... Shooter is lucky it wasn't worse!

| One more reason why you should wait when you get a FTF, if he would've waited a couple of minutes and the round did go off it would've gone down range. Don't get in a hurry when you're shooting something that could take your friggin head off, let this serve as a reminder for all of you guys just getting into .50's. |

if he would have reached over the gun ... that thing might have hurt him worse who knows... but def. dont stick your head down there. If he would have waited 30 seconds the hangfire would have burned through and fired the round. No need to reach over if you wait 30 seconds or so before opening bolt. -David Edgewood, NM |

Standard FCSA match procedure on hangfires/misfires. Clear the area behind and beside the gun. Wait an appropriate amount of time. Open the bolt from the non-ejection port side of the gun reaching over to operate the bolt. -David Edgewood, NM If I remember right last year at the World Championships I was shooting next to you and you had one? Or was it the Spring match? Anyway, David followed the proper proceedure and all he got was a round out of his group. Lesson for All here, ChiefBDT |

We see the broken rifle and the man with serious injuy to his jaw. But what caused this round to not fire when the primer was struck and instead go off when the operator lifted the bolt? We may never know for sure but could it be:
1) hammer hung up anf did not fall on the pin until the rifle was manipulated (bolt lifted), or 2) primer striked properly but primer defective and did not ignite the powder until a delay of several seconds, or 3) promer struck and went off properly but powder did not ignite until rifle jostled to open bolt, or what else could have been the flaw here. I ask so that us 50 shooters can look into preventing this if it is a rrifle issue or just keep poor ammo out of our rifles. |

He might be in the Military but I doubt he was being shot at, if you're on the range there's no reason why you can't take the time for safety. If it was a combat situation then yes, there isn't time to wait if you're taking fire. I didnt say he was being shot at. I just know how much time I gave a round when I was in the USMC which wasnt that long of a time...... I do remember a time at a T.O.W. shoot we had a hang round......waited 15 minuets until I lifted the breaker. I do know of a TOW round that went off in the hands of a TOW gunner one time in combat.......  this was back in the first war. Damn..i just dated myself.....

Glad he came out okay.

How did it cook off I wonder? .50 machine guns see alot more heat then this. Well the term "Cook Off" has several meanings. You named one about a new shell in a very hot chamber and the powder being cooked off to the point it burns from just the heat. And when someone using a handgranade lets the spoon fly and holds the granade for several seconds before throwing it. He is allowing the fuse to cook off some before throwing it. Lets say that there is some crappy powder just in front of the primer. Now it burns, but burns very slowly to the point that it almost goes out. But the fire just barely makes it way past the bad powder into the main charge and once it hits the good part it takes off like a wild fire and builds pressure and Kaboom. Now the time it takes varies. But as you have heard from the group mindset, a couple of minutes usually enough to give it time to or not to fire. So, it was in this meaning of cook off that he was using. Max |

You can cook off a Barrett. We had tried it once some time ago. Fired 300 rds in 2 minutes. Let a round sit in the chamber till it did cook off. Took about a minute or so. It was a test for a foriegn government.
But a cook off in a Barrett will still be with the bolt closed. Unless you hold the carrier to the rear. In the original post it was most likely a hang fire then the soldier opened the bolt carrier and then the round fired. The cut most likely came from the extractor flying off the bolt. Excessive pressure will do that to the extractor of the m82a1 family. We saw it a lot with suppressors. |

If it doesn't ignite after 30 secs is it safe to say it's not going to? I'm getting a AR50 and after seeing those pictures that's downright scary. |

After waiting the appropriate amount of time and then opening the bolt, you can try to shoot it again. With my ALS, I can reach into the action WITHOUT opening the bolt, recock the hammer and try to fire it again. If the round hangfires, the bolt is still closed. If you don't want to try and shoot it again, and you don't want to give it a second try (usually they will go off on the second strike), just stick it in an empty box and pull it down when you get home. -David Edgewood, NM |

-David Edgewood, NM You can do this with all AR lower type 50 uppers too... 
Just pull the rear pin and recock the hammer by hand, the bolt never moves... |
