This is good. I agree.
This is even better. How not to agree.
These are very valid points to which I entirely agree, but, interestingly, these are not the points that I would use to define the cartridge. To me, the bottom line is best captured with these two sets of numbers (i.e. data):
.378 Wby 300 gr; velocity @ 150 yd: ~2,400 fps; energy at 150 yd: ~3,900 ft/lbs
.375 H&H 300 gr; velocity @ 50 yd: ~2,400 fps; energy at 50 yd: ~3,900 ft/lbs
So, in the real world: .378 Wby at 150 yd = .375 H&H at 50 yd.
Let's talk about that:
I do not find ridiculous the thought of shooting a buffalo at 150 yd in open space (e.g. Tanzania long grass; Zambezi Delta; etc.), and many do so, very ethically. My understanding from discussions with 3 different PHs (all duly licensed and members in good standing of PHASA, i.e. these are real PHs, not 'internet' PHs - wink wink), no later than 4 weeks ago, when I actually shot a buff with an open sighted .470 NE at ~30 yd (see video at
https://www.africahunting.com/media...frican-safaris-in-limpopo-south-africa.69034/) is that
150 yd is in the real world a very common distance for buffalo, especially in open country, and especially toward the end of the season, and I can see a lot of good reasons why one would want to hit a buff as hard at 150 yd with a .378 Wby as a .375 H&H hits at 50 yd.
We can certainly all laugh at funny 'one-liners' re. 350 yd DG PBR, quarter mile DG shooting etc. but these are 'lah lah land' one-liners. If the conversation is serious, we are discussing 150 yd. And this is a fact. And it is not unrealistic. Folks who have not hunted in Africa would be surprised how often shots are taken way past 150 yd, including on buffalo. And I hasten to say that I am not arguing in favor of it, and I have the video to prove that my personal preference for buff hunting is different ;-) but, come on!, 150 yd shots probably account for at least half the buffs taken in Africa, I would venture to guess... At the very least, most of those taken in open space, as opposed to the dense bush.
Of course the argument will be that the .375 H&H kills buffs fine at 150 yd. This is absolutely correct. Heck, the mighty .375 H&H carries about 3,000 ft/lbs of energy at 150 yd. This happens to be just about what the 9.3x62 delivers at 50 yd, and there were likely more buffs killed with the cheap Mauser 9.3 by local settlers (Afrikaners, Germans and Britishers) who could afford it, than there were with the .375 H&H of wealthy tourists.
But judging by so many outfitters promotional reels on You Tube, 150 yd / .375 H&H buffs tend to degenerate into long running gun battles... At 150 yd, the good old .375 does not pack the punch that it does at 50 yd. Just plain obvious fact. Which is why so many pros agree that even though the .375 H&H may be 'the best all-around African caliber', if you are going to concentrate on dangerous game, you better get something bigger, like a .416, .458 etc. - or dare I say .378? - because, guess what?, these still carry the mail at 150 yd...
Which brings us very logically to the excellent point made by
@Russ-F:
What do we have in mind to deliver in term of trajectory and energy at 150 yd? .458 Lott/.450 Rigby? Good choices, but guess what? they recoil just about the same as the .378 Wby: 70 ft/lbs of free recoil in a 10 lbs gun for the Lott vs. the .378 Wby 71 ft/lbs. And don't think that they recoil slower either. I know, I shoot a .458 Lott (
https://www.africahunting.com/media/cz-550-416-rigby-rifle-mauser-66-458-lott-rifle.61217/), and I have actually shot a .378 Wby: both guns' recoils are impressive! I would personally pick a .416 Rigby for open space buff, but do not delude yourself about its recoil either: 60 ft/lbs is still no pick-nick.
Here is my suggestion: go shoot a .378 Wby and a .458 Lott in succession. You will be surprised how, after all, the .378 Wby is not all that terrifying. Sure it is, when you transfer without experience or proper training from .270 Win to .378 Wby, but try to hand over a .458 Lott, or even a .416 Rigby (never mind a .500 Jeffery or .505 Gibbs that seem to enjoy a revival these days) to a .270 Win shooter, and observe the results LOL.
Not trying to be argumentative here, just bringing data and real world considerations to the chat... Yeah, the .378 kicks, and the scope better be waaaayyyy forward, but I like the idea of delivering 4,000 ft/lbs at 150 yd. Take your pick: .378 Wby (smaller/faster) or .458 Lott (bigger/slower) but whichever you pick (another fascinating debate?) be ready for the same 70 ft/lb of free recoil...
