Yes, the 460V comment was directed to Gigantor. I posted it separately but the system merged the two posts unbeknownst to me.
I don't have any reservation that the 47oz Toklat will be too small much less the 460V. I am fully confident a 360gr hard-cast, flat-nose 454 Casull round will take down anything that walks on North America.
A 190 gr Buffalo Bore round from a 30-30 produces 1,860 ft/lbs of energy at a velocity of 2,100 fps.
A 360 gr Buffalo Bore round from a 460 S&W produces 2,860 ft/lbs of energy at a velocity of 1,900 fps.
A 300 gr Buffalo Bore found from a 454 Casull produces 1,813 ft/lbs of energy at 1,650 fps.
A 430 gr Buffalo Bore round from a 45-70 levergun produces 3,537 ft/lbs energy at 1,925 fps.
I would pick a 45-70 if I wanted a long (brush) gun. The 460 S&W outshines the 30-30 while the 454 Casull is about equal. In the end, I'd take the other three over the 30-30 because they produce a substantially bigger hole.
