Damn…. I need to cheat off of your work. That’s great speed. I’d launch them into elk, no problemo!
Where's gunner. I think he has a good load with H4831?? I know my 308 Norma loves that powder. Can't beat that 200gr Nosler partition either. Do not be worried about reaching screaming hot velocities either! If that bullet goes clean through elk at 30-06 velocities, the 300H&H is going to be that much better. I used to run 2,900fps in my 300 win mags. If I ran 2,800-2850 in the H&H with excellent accuracy, I'd call it a day.
The 308 Norma magnum has about the same case capacity as the H&H. This is the load I run:
It's running right around 2,800 fps. Like I said, if the 30-06 hammers them at 2,650 fps, the H&H and Norma magnum will work that much better. Although "better" is awfully questionable after you've hit them with the 30-06. Hard to imagine much better than DRT.
