RE: 300 WSM Vs 7mm Rem Mag Which is better for big game
A comparison of the 150gr Nosler Balistic tips in both calibers (from the Federal Website):
The .300 WSM starts with a 225 fps advantage and about 500 ft lbs of energy ( at the muzzle) -Which isconsiderable.
At 400 yards the .300 WSM has a 100 fps and 150 ft lb advantage with basically the same trajectory (.5 of an inch to the 7mm @400 yards)
I also prefer the .30 cal for elk / moose sized game along with the heavier bullets - not available in 7mm and I've never had a problem finding .300 WSM ammo. Its here to stay.
In comparing several other bullet weights, the .300WSM is clearly more powerful.
