I am in the market for a .375 crf. The limited options that I have seen (Kimber, CZ, etc.) do not light my fire. I was looking for a .375 H&H, but the Ruger advertising makes me want to know more about their offering. I know the ballistics, and the rifles, but what do you think of the Ruger cartridge in terms longevity and of ammo availablilty in Africa?
