I'm going to save your bank account. Get a 375 H&H and sell all the rest. You can literally use the 375 for everything. Load it with a solid and you can take rabbits and squirrels. All you will have is a nice round 37 caliber hole. I've done this and there is less meat damage with the 375 than those fast 22 bullets cause. Load a soft point and you're good for 99% of the rest of the game on earth. For the really big nasty stuff in Africa go back to the solids.

My 375 shoot both solids and softs (handloads) to the same point of impact. If I could only have one rifle for all my hunting it would be a 375. My second choice would be my 9.3x62 for the exact same reasons. Add a 12 gauge to the mix and that one rifle and shotgun combo will allow you to hunt anywhere in the world.
