I should add, if you have no loaner rifle available in Mozambique, and also are new to medium bores and up, be cautious with the Alaskan. If your ammo doesn't arrive (must be packed separately), you'll straight up not be able to hunt. Missing luggage happens a lot on the way to Africa especially the small luggage pieces like ammo, you'll likely be going through three different borders/customs to get there, not including leaving Canada, and at least three separate flights. .375 H&H will be readily available locally of course.
Recoil is another factor with the Alaskan. Some shooters very experienced and comfortable with the standard magnums and even medium bores in larger rifles, want no part of the Alaskan for sake of the recoil. I think it's a slick little medium bore carbine, but likely sharp on recoil, with impossible to source ammunition. So on further contemplation, I'd suggest hunting for the BRNO 602 geologist mention, and shortening the barrel if it suit your tastes. I sold one to looch for about $700 if I remember correctly, they can be had affordably. Any changes in the plans for practice? My .375 brass lasts five loadings no problem, I'd buy a hundred brass, 500 Hornady cup and cores, and practice and learn since you handload.
And, going to your first post update, make sure you're in shape before you head over! You'll be walking a lot longer, and a lot further than you likely imagine, and she's damn hot in Nyati country. Good hunting.
