I have a .375 Ackley Improved (rechambered) inmy Sako fiberclass --- i get a measured 2950 ft/s with a 300 gr sierra that shoots sub moa at 300 yds (my usual practice distance). That is over 250 ft/s from the .375 HH. Now, I tend to agree that velocity is not everything when you are shooting 200-250 yds, but I have used the 375AI with great effect on that nmosse or elk standing across a vally or river at 300 plus yards.

I built it thinking it would go to Africa -- it still may - but I agree that you dont need that range in Africa (but maybe -- just for that one monster.....at 400 yds) but in western Canada, where some of the shots can be long, it works quite well, with really very little increase in recoil. I think that my re-chamber of that rifle was the best $150 i ever spent on a rifle.

In Africa, I prefer 9.3 or .416 and my .470 (just in case). But again, last time, my .300 weatherby took serious game out to several hundred yards when they were spooky, so the ranging ability and the ability to shoot that far played a very important role in the success of my hunt when some of my mates were trying to get closer (and having little luck)

I would opt for the .375 weatherby and shoot .375 HH if that is what you feel like doing , but be ready for the extra 250 ft/s if you need it -- especially if you use a 270 gr bullet - the difference would be well worth it imho.
