Very,very nice.I am a big fan of shotguns.Far more deadly a firearm than it's handgun or rifle counterparts.((depending on range of course))
The poster of the vid asks why the man being shot didn't recoil from the blast.And there are several reasons for this.Especially in this case where it appears to be a riot situation.
Despite the barrel being sawed off,the blast from the gun sounds like a 20gauge and not a 12gauge.Also because this is a riot situation I am guessing that the size of the shot is either #6 or #8.
But yeah that guy is going to die.There were prolly 60 shot half the size of a B.B. inside that guys torso.
It was clearly a 12 gauge shotgun. The barrel was not sawed off as you say but a Winchester Defender with 20 inch barrel, or a Remington 870 or any toher number of combat shotguns.
