Not sure why, but I feel Under-gunned with my 375 H&H. thinking of rechambering to a 375 Weatherby or 375 RUM -- lets hear your thoughts or experiences on this. Thanks
It's a religious debate that you're bringing up on this topic. You've made a thread that implies a belief in Roy Weatherby's "Speed Kills" philosphy. To be more hyperbolic for sake of example, if there was a 375 that went 4000fps, your view would be that is even more better better.
On the other side of this religious war is "large diameter bullets moving at moderate speed have greater hang time in the animal and in heavy for caliber configurations they do more damage". If you read Pondoro Taylor or look at any of the classic magnum calibers, they adhere to this concept of big bullets at 2150fps. (450NE, 470NE, 500NE, etc.)
I'm in the latter group. I don't think you're going to make a 375HH better by making it shorter, longer, or faster. It's the best at what it does as a caliber and cartridge as it is.
While a 375Wby or 378Wby looks better on paper than say the fairly lethargic 404J and 450/400, the 40 cal options just have a better reputation on Buffalo than any 375 of any speed.
Bottom line, you need to make a bigger hole with a heavier bullet, not shoot a small bullet faster.
