Not that I know of. It was TexasCowboy’s rifle and he handled the return to Springfield. The ammo was new and theoretically even I shouldn’t have been able to “operator error” this catastrophe.

Springfield paid me back for the surgery that I required and I dropped it after that. Then TexasCowboy got sick and I really dropped it after that.
Didn’t realize it was Texas Cowboy’s rifle.
It was my understanding that they never came up with an answer.
The only think I could think of would have been a metal shaving inside the bolt locking the firing-pin into the “fired” position, causing a slam-fire, but even that explanation has weaknesses.
OMG.
Himself just had a hang fire in his and we figured Dad had loaded a dud.
The primer was dimpled but that was it.
No bang.
