Very nice calibre, what a outstanding "plan". I'm guessing you're pretty familiar with 7x64 from the Big Bore Shoot . . . I really like my CZ 7x64, dammed near 7mm Rem mag velocities, easy to reload for and great to carry. According to Quickload 7x65 (69.8) has just smidge more capacity than 7x64 (69.0) but runs at 55,000 psi compared with 60,000 psi. 280 Rem is 67.8 and 284 Win 66.0.
Cheers
