Sounds like a very nice rifle.
I personally would stick with the 375 Ruger for my cartridge choice.
I have an Alaskan 375 Ruger that I had re-barreled, was suppose to be 23" but turned out 23.5", McMillan Ruger Classic stock, barrel band NECG front sight, factory rear sight, Spec-Tec trigger.
I like the rifle, but use more often a 20" factory Alaskan with a McMillan stock and Spec-Tec trigger. I have been using the 270 grain TSX for moose and no complaints with them. I do have some of the 270 LRX that I want to load.

The 375 WBY has been temptingly. I still occasionally think of rechambering a M70 stainless 375 H&H to it. But, with equal barrel lengths, I don't think that I would gain much over the Ruger cartridge.
