Soumds plausable since there is no pressure curve as all the gas and powder is by passing the bullet. It looks about the same power level as a 2 3/4 slug. Definately not the same as when launched from a 50cal chamber and bore.
"Gun control: The theory that a woman found dead in an alley, raped and strangled with her panty hose, is somehow morally superior to a woman explaining to police how her attacker got that fatal bullet wound." L. Neil Smith

Breneke makes a sabot with a solid copper one ounce 50 cal slug. Hornady makes a similar round that has a range of 200 yards.

I do not shoot with my hand; I shoot with my mind. He who shoots with his hand has forgotten the face of his father.
I do not kill with my gun; I kill with my heart. He who kills with his gun has forgotten the face of his father."
