What kind of AR was this? How old? Is it chambered for .223 or for 5.56mm, and what was the caliber of the handloads? Also, do you have the recipe for the handloads? I'm sure I'm missing another 20 important questions. I'll step aside and let the cognoscenti take over. |

Sounds like an accidental doublecharge.

Bolts break from time to time, Sometimes at the lugs, and sometimes at the cam pin hole. If you look in the TM, you'll see that the bolts are to be inspected for cracks at the lugs and the cam pin hole. |

I have heard of the bolts snapping at the cam hole, but have never heard of them snapping off the all the lugs at the same time.
Any idea of where this bolt came from? I sounds like the bolt was heat treated too deep, and caused the metal to be too brittle. |

Well, one thing it WAS NOT was a double charge ! You can't get all the powder you want into the small 223 case. Hell, with commercial brass, all you have to do is dip brass into WW 748 , level powder with top of case, jam in a bullet and you are set to go !! But really, you are hard pressed to get the max load into those cases.

A lot of suppositions here, but without the body and an autopsy, we'll never know.
I'm leaning towards the incorrect heat treat theory. Then again, anytime handloads are involved, they are automatically the prime suspect. Could there have been a second shooter? |
