Factory choke?
I'm assuming you "reloaded your gun" with Kent factory ammo. I'd send that picture to them and ask if their shells are supposed to do that.
Well first things first, glad you are safe and in one piece. Never have I seen that happen. Are you 100% certain that a wad lodged in the choke of that gun caused that much back pressure? The reason I ask is that for all that gas to come back to you you need a blockage and a wad should not be a strong enough blockage. By the very design wads are made to travel down the barrel and exit. Not sure of the make of gun you are shooting but if it is a gas powered auto I would definitely have a good gunsmith check your gas system out thoroughly. If it is a pump then I wouldn't even speculate as to the cause.
Holy Crap! That is gnarly glad you are all good. So stupid question was it the gun or the load that caused this? What load were you shooting? I usually shoot Kent as well...
