I have this .22 lr rifle, AMT small game hunter II, with an Archangel stock . Copy of the Ruger 10/22 in stainless steel with a match trigger. Very nice rifle, accurate but a bit finicky at times.

This morning I had an out of battery detonation, a little kaboom. Unusual noise, powder, smoke and debris.

Result :

That Remington bullet almost made it out of the barrel

After an unusual event / noise or recoil report I always check the barrel for obstructions. This one was rather obvious

Stay safe guys
