Would a Ballet retain any sort of accuracy over that much charge?
I don't know. Like i said, I think I would reduce the charge.
TKO, hmm....seems to me you kill an elephant with a 2x4 very easily. Plug 3.8 in there forcaliberand a velocity of about 20 ft/sec on a good swing.
"A Taylor KO Value of 33 with a bullet that weighs 3000 grains, a velocity of 20, and a diameter of 3.8."
Ah figered wate on the lite side so az ta be conservative.
Stop, stop, please your killing me

Happy Hunting, Phil
