That is about 100 ft. lbs. more than either SST bullet in your calculations. It is actually about 2 ft. lbs. less than the 145 Speer BT, at 2900 fps. from a 7mm08. In this instance the 6.5 CM and the 7mm-08 are ballistically superior to a 308 with the 150 SST bullet and are ballistic twins. They do both have less recoil andI used the 7mm08, with the 145 Speer for years, and had no problems taking moose to 600 yards. I would likely take the 6.5 CM over the 7mm/08 as it would have the least amount of recoil and I can buy factory ammo for it.

I've got 400 143gr ELD-X so I hope my rifle likes them!
