The .375 is every bit as flat shooting as any 'o6, and deserves a scope that can see as far as it can be lethal. A pretty long ways. On the other hand, a big wide field of view might come in handy in Alaska from time to time.
I had a Leupold VXIII 2.5X8 on mine, as I was sure if anything needed a VXIII the .375 was probably a candidate. The difference between that and a 2X7 is pretty much theory, I can't really see any difference myself. at 7/8 you can see well enough for precision load development, at 2/2.5 you can see lots, close, fast.
