Not a totally responsive answer but … For 20+ years, I've used a 6MM-06 on every big game animal I've shot except Elk; including Mule Deer, Whitetail, Antelope, Caribou and Big Horn Sheep, I couldn't be more satisfied with a caliber. A 100 grain Partition @ 3270 fps. has taken them all. Mine's a Rem 700 with a #2 Douglas barrel.

The 240 is about the same cartridge -- I'd surely buy it.
