From Sir Bob's blog, latest installment, linked above, some highlights:



"... we now have the 404gr Shock Hammer from Hammer Bullets, in .458-cal, at .419 BC.
At near 2600 fps it’s capable of taking large game, like moose or eland, to 500 yds!"



RIFLE: Ruger No.1H

Cartridge: .458 Win Mag

Bullet: 404gr Shock Hammer

SD = .275

BC = .419

MV = 2580 fps/ 5972 ft-lbs (what I’ve gotten from the original 400gr X-Bullet in my Ruger No.1H)

100 = 2385/ 5102 ft-lbs/ +3.8″

200 = 2199/ 4377 ft-lbs/ +3″

300 = 2021/ 3664 ft-lbs/ -5″

400 = 1852/ 3077 ft-lbs/ -21.5″

500 = 1693/ 2572 ft-lbs/ -48″

"The ambient conditions for the above data would be average for my area. The heat of Africa would much improve those numbers."

Yep.
Load the 404-gr Shock Hammer to 3.58" from 2.5" brass in a .458 WinMag chamber and do not worry about pressure at 2580 fps.
Putting that same load into a SAAMI .458 Lott chamber is going to be dicey.

3.58" COL for the 404-gr Shock Hammer is a nice COL to work with in a Ruger No. 1 .458 WinMag, aka .458 WM+.
