Boyds would be worth it for the 6.5 CM, so worth it as well for the .300 WM. I put a featherweight pistol grip (fish scale w/Pachmayr) on my .260 Rem whitetail rifle. Aluminum pillars and glass bedded.

Barrel profile? You have to carry it. Heavy is great for target. Necessary for 20 round strings. But for one or two at game after carrying the rifle four or five miles and thousands of feet in elevation change . . . not so much. And then getting the rifle and the carcass back to the trailhead/camp/car/home. Ounces matter.
