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
The problem with being stupid is you cannot simply decide to stop doing dumb things...
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 aim with my hand; I aim with my eye. He who aims with his hand has forgotten the face of his father.
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."
