458 Win Mag vs 458 Lott....The facts

[Riflecrank]

@Riflecrank what powder and barrel length are you using to achieve 2980 fps?

H4198, 300-grainers, 24" barrel.
The load odonata quoted was from Sir Bob in Ontario. I have duplicated his data.
You can top 3000 fps with the 250-gr GMX from Hornady with H4198 or AA-5744.
That monometal bullet with a plastic tip is tough enough to take it.
Velocities around 2700 to 2800 fps are more sensible since the higher velocity loads only get you about a 50-yard advantage.
Those low BC bullets lose velocity so quickly when started off that fast.
