True enough. But then, there's always something out there a little bigger if that's what you want and this is especially most notable in the 30 cal selections available. I decided to pick up a model 70 Winchester Super Express in 375H&H that came available as
I thought it would be a good mate for the one I already had in 458WM.
Then, after reading a few articles on the 375CT and/or the 375-338, plus seeing some of the info on this wildcat in P.O.Ackleys books, I
decided I 'needed' one.
Admittedly, I haven't done much with it yet in the way of reloads and testing but that should change with
better and IMPROVED access to our range and after I have a cataract issue delt with.
Does anyone know the water capacity comparison to the base of the neck between these two and does anyone have a reamer for the former?
The correct answer to this question is 375 Weatherby,....and I have a reamer for that one...

300WM fire formed in 375 Ruger 105gr I believe.Let me Google this for you
.375-338: 88gr of water
.375 H&H: 95gr of water
.375 Ruger: 99gr of water

1. 24" bbl.
2. Load was hot, not magic. I didn't use it as a 270gr @ 2700fps has always just fine in a 375Magnum. If one needs more, the 378Weatherby is an option.

Nice!
but to me misleading...
I have learned that RL 15 is one of the best powders for the 375's but it is very temp sensitive. Caution should be used when dumping 75+gr of it in a smaller case and using it in the heat.
Its far easier to get that velocity from a 375 Ruger or whatever that was designed for it.

The model 70 I have would need action modifications I'm not willing to have done at the moment.
Really?
Alliant lists 71gr RL15 as max for the 375 H&H and a 270gr bullet, for 2675fps. No surprise you got a fast mover there

Alliants max is conservative, I'm loading 76.0 RL15 in both 375 H&H and my 375 Ruger, no pressure signs in either..
What velocities are you getting?
I got that info from C-FBMI's 375 Ruger Hornady brass problems thread. On reflection I think he was using a Win powder to measure , not water. My bad.
Buckmastr............I absolutely have to disagree with you on RL 15 being temp sensitive. I have a load that produces 2925 fps with a 270 TSX from a 24" barreled Rem 700 375 H&H at about 15 deg C. Admittedly this load is warm but the accuracy is outstanding and the energy is huge with a trajectory better than a 300 H&H 180 gn load. I used this rifle and load in Zambia in 55 deg C + temps with no pressure signs at all, I also used the same load in the Congo and SA and Namibia.........no grief at all, no spikes and no stiff bolt lift. I must also add that this was chronographed through an Oehler 35P, not a Chrony or some other questionable speed measuring device.
