Alrighty then. Is this the rifles sole purpose? Otherwise, you'll be able to get off the .375 H&H. I realize you want enough gun with the grizzlies of Alaska, but man, a .338 Win Mag, .338 Rem Mag, and .300 Winchester Mag will kill a grizzly just as dead (I think) as the .375 H&H. Not trying to dissuade you, but geez man, you trying to knock your shoulder off? Imagine trying to sight that sucker in :eek: . 10 rounds at once and you'll wind up in traction :shock: .
But if you'll be hunting bigger and maybe even dangerous game with it, then ignore the previous paragraph. In my judgment, I'd go with the XCR, but as I said before, you're not me. The decision is ultimately yours to make.
