Yes, Daryl,
spot on about the lack of comparison with the 338. I'd be interested to know how I might safely get 2000fps out of my M94 375 Win with 250-grain bullets, though, esp if it involves Reloader 7 powder. I haven't checked for a while but the best I can remember was about 1860fps from the factory loads, at least.

CR, maybe you should look at something like the 375 Ruger or 458 Win made up into the BAR or its pump-action brother. If they are legal where you go in Africa, they might be OK, esp. if you use only new or full-length-resized ammo.

I know you already have a .45/70 but have you thought of this:

Marlin make good ones, too, but I think the Winchester looks sexier.
