The 404 gr Shock Hammer at a no-sweat / easy 2300 fps, scope sighted 2" high at 100 yds, seems like a very easy 200 yard trajectory, wind drift, and remaining velocity for about anything with hooves.
For me this bullet upped the 458 uses ...
Amen, Sir Larry. That is essentially what I did for my most recent deer cull.
I consider the .458 B&M+ with COL of 3.08" to be identical to the .458 WinMag at COL of 3.34" with whatever bullet is being used, regarding load data and results.
My load with the 404-grainer starting off at about 2350 fps passed right through that deer at 200-yards, dead on and dead right there. The 80.0-grain AA-2230 charge will give about 2350 fps in an 18" barrel and about 2500 fps in a 24" barrel of a .458 WinMag shooting that 404-gr Shock Hammer. Make it 3.38" COL to work in any factory .458 WinMag magazine box, or 3.48" COL if you and your rifle like that COL better. If you go as short as 3.28" COL then less powder will be needed to equal those velocities in the .458 WinMag.
Usual safety disclaimer: Whatever COL you like, work up from 10% below my favorite charge of 80.0 grains AA-2230, for goal of 2300 fps to 2500 fps MV with the 404-gr Shock Hammer.
