Er, you plan to hit a rapidly moving armored tank with razor tusks and an attitude with a short pistol gripped scattergun, whose accuracy and firepower has been seiously degraded by the barrel shortening?

I think a second shot from your primary hunting weapon may be in order. A shotgun would be wonderful, but definately not the "instant knock out" fix that you've pictured... Longer barrel to keep the shot together and on target.

If you try it, I wanna see video. And I get the shotgun in your will, OK? - sawed offs have deffinate good uses, though this ain't one of 'em.
