I thought might be the case. I live in New Zealand and kimber would sell a lot more rifles if they made the classic in a greater selection of calibres.
They don't really make a whole lot of rifles. The ones they do make are really, really nice, though.
In the past they have made the Classic in some calibers, and then discontinued those calibers in the the Classic and sold them in the higher grades. I think they keep selling them in the higher grades until the barrels are gone, and then they stop selling that particular caliber. That's what they did with my .338 Federal, which is an excellent cartridge.
