I'll go through my old loading data and see if I still have that stuff...I really gave them a wringing out and had a lot of load data. It will take me a day or two...

It also has a lot of loading data for the 375/338. I think they are calling it the 375 Taylor.

Not to stir up any trouble, but, we just had a client return from a Zimbabwe safari for 14 days. First of all he had a wonderful time even though it was his 5th safari to Africa. He told us stories as if it was his first time.
We built him a .375 Dakota which he thought would be nice to try on plains game. Fortunately he and the PH got onto a great buffalo which was not in the original plan. On site the spread measured 42" with bosses "as big as volley balls". It was a one shot kill through the bottom of the heart and through the lungs. It went about 75 yards through the tough stuff and was found on the ground next to a tree, dead. The PH suggested that our client use this rifle/cartridge for the remainder of the safari. I will get the rest of the list of the trophies this weekend, sorry. He used one cartridge for each trophy except one which took two. More to follow.

Apparantly two powders stand above the rest and that is IMR-4064 and IMR4895..so it's a pretty simple loading equation...
WW brass and Fed. 215's
67-4064-300 Nosler=2604
67-4895-270 Hornady=2600
68-4895-300 Nosler=2666 max.
69-4895-300 Nosler=2712 Too hot prim. exp.
68-4895-260 Nosler=2819 fast and accurate
RL-22 77grs. 300 Nosler= 2493
68.5 VArget 3oo Hornady, fed 210 = ??
My notes indicate I settled for 67 grs. of IMR-4895 for everything as it was the most accurate with all test loads and velocity was right up there with the H&H in my rifle....simple.
Start 10% below my listed loads and work up as they apply ONLY to my rifle...
this combo worked on the several I built for clientele and one for myself which I sold because it was a wildcat that duplicated a factory round...

The precessor of the classic .375 H&H was a standard length belted magnum, the 400/375. It would be somewhat interesting to know if and how that old one differs from the .375/.338.
Your project sounds interesting.
