Home Forums Hunting & Shooting Ask The Gunwriters 7mm WSM or 300 WSM

Using Federal factory ammo as a guide, their 7 WSM 140 Nosler BT @ 3310 fps generates 3405 ft lbs. of energy while the 300 WSM 150 Nosler @ 3200 fps generates 3410 ft lbs. The 7 WSM 160 Nosler Partition @ 3160 fps generates 3545 ft lbs. of energy while the 300 WSM 180 Nosler Partition generates 3540 ft lbs.

They are basically equal in energy. Therefore, recoil will be very close. Assuming a zero of 250 yards, the 300 WSM will drop a little more than 1 inch more than the 7 WSM @ 400 yards with the lighter bullets. The difference at 400 yards in drop with the heavier bullets is still less than 2 inches in favor of the 7 WSM.

I think a fellow needs a 7 Mag and a 300 Mag.
