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

Sir Scotty,

Me too. Hammer Bullets are as precisely manufactured as you will find.
I will start corresponding with them about making a 400-grainer of higher BC than the current .458-402g Shock Hammer.
2500 fps in the .458 WM Sub-3.4"
2600 fps in the .458 WM+ "Crusader" Sub-3.6"

Note that in the SAAMI .458 WM throat, at 3.450" COL
the "Mammoth Cave Hollow Point" .458-402g Shock Hammer is jammed into the rifling at end of throat.
Seat it one band deeper and it will be good in any SAAMI .458 WM and still too long of COL to fit in the .458 Lott throat unless you trim the Lott brass shorter !

A pointier 400-gr Shock Hammer with a smaller diameter hollow point and slightly greater Bullet Overall Length is to be proposed.
Something similar to the 400-gr GSC HV but with the patented PDR drive bands of Hammer Bullets,
famously tolerant of any COL you like, even jammed into the rifling.

The GSC HV pattern:









2725 fps with 65.0 grains of AA-5744 is a most accurate and meat friendly limit with 250-gr Hornady Monoflex
for short-range deer hunting with the .458 WM at 3.340" COL.
69.0 grains gives just over 3000 fps but makes too much burger mixed with bone meal, and doubles the group size.
