What are the barrel lengths?
My dad has one with the 18.5" barrel, too short IMO. He loves it though.
It's a good cartridge I think, similar to 270win performance I think.
A few years ago Remington was loading ammo for it at reasonable prices, I think when the WSM line came out. 120gr core lokts
I personally think I'd take the newer version of the rifle with the 22" barrel over the 18.
