Strange as my buddy in Missouri recently had two 6.5x284's built one for bench and Hi Power the other for hunting. Both have identical chambers and rounds will chamber in either. Now if the 260 is so superior I wonder why he didn't have a couple of them built?
As it is I see no reason nor need for either moder copies, that is either the 260 or 7-08, I will stick with the oldies. You play with yours it keeps you happy
