@Newtothis first let me say that I'm about to purchase my second double, which makes no sense cause I can only shoot one gun at a time and my first is a 500NE. So you probably shouldn't pay any attention to what I'm about to say cause clearly I'm not thinking straight. And there does seem to be this "thing" that happens when you buy a double- you almost immediately need more of them- I don't know why- so I'm going to do my best to warn you off of them.
A 375 (or a 416) in North America? Really? Why? (I'm gonna catch hell for this one) I mean I could shoot a LAW rocket at a brown bear or moose I suppose but why? I've heard rumors of Cape buffalo in Texas but there are no American Buffalo. There is a Bison which some folks seem to confuse with buffalo, just like some folks confuse Pronghorns with antelopes or goats. (folks I'm just having fun here)
IMHO, the sweet North American caliber is a 300 magnum. Okay, maybe not for a Bison. Could be considered a little light for a Yukon Moose or a Brown Bear. For those I prefer a Jim Brockman Marlin Guide 1895 45-70 SS Gun. A sweeter, smoother lever gun I've never seen.
And if it's sacrilegious to take a lever gun to Africa isn't it just as sacrilegious to use an African gun in America?
I've kinda drifted of course here haven't I? Can you tell I'm still on my first cup of coffee? I did OD last night on Buzz Charlton videos. Am I rambling?
Ok, ok sorry, I'll get back on track.
@Newtothis if you plan on hunting Africa some day. If you even think you might hunt Africa someday. Heck if all you'll ever do is dream of hunting Africa someday, I say buy that 470 Double. You too can watch hunting videos while caressing it. (did I say that out loud?)
I didn't help at all did I.
