Rugers and Savages also have 1 in 10 twists. I personally haven't seen any practical difference between and 1 in 10 and 1 in 12 for a .308. Unless you are going to go with some real long bullets like Bergers or 220 grain bullets, I would go with the gun you like and not fret over whether it is 1 in 10 or 1 in 12. And those long bullets are generally not suitable to the .308's short neck anyway.
