Home Forums Hunting & Shooting Express Rifles and Big Bores Only The great 458 Winchester. Everyone should own one at least once

Those CEB 600-gr Lazers cost about 3 bucks each.
Better to use some 600-gr cast bullets for the ballpark powder checking.
Time for me to cast some.
BTW, having mentioned Sir Jerry's champ 500-gr TBSS load above,
note that his Holiday Casting was an interesting scale up of the Saeco "Model of 1881" Gov't.-style 500-grainer
from .458 to .512 caliber, in 16:1 alloy which sure do make pretty bullets.
The 500-gr/.458 in whatever alloy grew to 715-gr/.512 in 16:1 alloy:







I am swagging that the weight-scale-up ratio for .458 to .512 would be a factor of (.512/.458) cubed = 1.39704 X
So in same alloy, a 500-grainer would become a 699-grainer, pretty close.
So I am suspecting the .458 Gov't. bullet in 16:1 alloy would weigh a little more than 500 grains, or about 511 grains ?
Got a sexy sub-.458-caliber cast bullet to scale up to .458-caliber weight ?

600-ish-grain .461-caliber and 158-ish-grain ".357-ish-caliber" are on my Holiday Casting agenda,
thanks to the picture with the pistol in it as a reminder to try the 6-cavity Lee mould while I am at it.
I find that a 158-gr cast bullet at about 900 fps shoots to the same 25-yard POI as a 125-gr JHP at a modest 1250 fps
in either a 4" Ruger Security Six or a 6" Colt Python.
Good zombie headshot medicine.
Hopefully a subsonic 600-grainer and a supersonic 600-grainer in the .458 WM+ or .450 WW2
can be found to have a useful POI combo at close range for zombie herd shooting when their melons get lined up.
