My $0.02 worth.
You've had a slam-fire. Check the bolt on the gun to make sure the firing pin is functioning ok. Check the chamber to make sure nothing is keeping the case from bottoming out in the chamber. Years ago I had a Savage semi-auto rifle that would go FA on me.....no indication when it would do it. It did it with one certain kind of ammo. I checked the rims on the shells and found that some of them were thicker than the ones that fired ok. It was firing out of battery.
