I agree with Jonesy, had it been the result of a "Hot" load it would have blown in the chamber, not way down there near the muzzle.

"The old adage "kills on both ends" comes to mind."
That normally applies to recoil which may well have actually been reduced on this shot. Not truly a very efficient method of "Mag-na-Porting" though.
