The logic for caliber choice is finding a good balance between wind drift and recoil. Actual drops aren't particularly important since you will have dialed in the range for the temperature and altitude already. The random nature of winds, however, continue to defy precise prediction. The best way to minimize wind drift is with a high ballistic coefficient starting out at a good clip.
I know someone who uses a 7 WSM and does reasonably well with it. He does indicate, however, that dealing with recoil results in a lot of fatigue at the end of the day. The 6.5 Creedmoor and .260 Remington show well in the drift equation with somewhat less recoil.
The 6mm Norma BR is an even better balance for recoil and wind drift, but those bullets will drift more than the 6.5 and 7 mm.
Have you looked at 105 to 115 grain bullets with appropriate twist barrels in the .243 Winchester? The recoil won't be much more and the wind drift is almost competitive with the 260 Remington/6.5 Creedmoor. The price paid is a slight reduction in barrel life.
