My vote is for the Ruger No.1. Yours just happens to be in .375 H&H which I think will be plenty of gun. With the 260 gr or 270 gr bullets trajectory will be very close to the .30/06 165 gr. bullet.
For what it is worth I use a No. 1 in a .338/06 with 225 gr. bullets.
If you had a No.1 in .30/06 that would be ideal. I think that would be a good excuse to buy another rifle.
