If I didn't go with a 7mm, I would jump to the 338. 330 Dakota, 338 Edge, 338 AX.
Since I do not know the OAl length of these cartridges, I am not sure they would work, but you could always put a single-shot follower in though.
With a switch barrel you could have a 7mm and a 338. You may have to get a extra bolt, but that is not a big deal in the big picture.
Myself, I have not looked into what impact velocities would need to be for reliable performance @ 1500 meters on game. At least not yet anyway
FWIW-I have owned and or shot @ LR the 260 Rem, 6.5-284, 284 Win, 7WSM, and the 7mm Dakota in field conditions.
