The Remington web site does not list the .260 as a option. .270, 7-08, .280, and .30-06 seem to be the current choices. If I could pick one of these, it would be a .280.
I'm not sure where you are at( located on this great planet), but if you don't reload of the 4 calibers mentioned above by Duval, you will have a much better factory loading selection per differnet game with the 270 Win in my opinion? But if you reload then I still suggest the 7mm-08 over them all. JMO
