Lightest possible loads for .375H&H?

[Rocky Raab]

Yup. I'm sure that was a temporary brain cramp.

The bullets for the 375 Winchester will work perfectly, as will cast bullets, of course. The Speer 235-gr semi-spitzer was specifically designed for deer-level loads in the mighty 375 H&H, also.

Starting from the bottom, I'd recommend 24.0 of Blue Dot under a 245-gr cast slug for 1750 fps. Next up in power, try the Hornady 220FP over 38.0 of H4227 for 2100 fps or 42.0 of SR 4759 for 2300.

You can launch the same 220 Hornady up to 2800 fps with 74.5 of RL-15 or H4895.

Finally, the 235 Speer can be launched at almost 3000 fps with 80,0 of RL-15, or down as low as 1700 fps with 30.0 of SR4759.

I'm sure that Accurate Arms lists reduced loads using 5744 powder, also.
