Hello, I just had an Interarms 375H&H rebarrelled to a 333 Jeffery. I have all the components to reload just looking for a reliable source for loading data. Any help would be appreciated.

Admittedly I know noting about it, but it has a case capacity of 84 grains of water, and a working pressure of 46K psi. Not sure why so low. It is a really big case, probably stuffed half full of cordite. Very inefficient.
338 Win mag is 86 with a much higher, 20K psi, pressure.
I would use 75% of 338 data and don't use slow powders.
Or I would just start with 338-06 data. Not like you are putting it on a spanish 93.
Lots of ways to do it but I can tell you one thing; I would not have waited until I got it back to get load data. Part of the fun.

Both the flanged and rimless .333 Jeffery are in the Woodleigh manual.

COW shows 52grs of 4350 for a 275gr bullet and 50 for a 300. It's very close to Keith's 333 OKH. Data for the Keith round is easily found.
