I feel the WSM is the best choice if you you have decided you are going to go 7MM. Itis in a dead heat with thelarger STW and 150 to 200 FPS ahead of the 7MM Remington Mag. The fact that it is available in the short action rifles makes it a better choice than the 7MM Remington Mag even without the better ballistics. This cartridge can deliver 2097lbs at 400 yards with Federal ammo with 160 Grain accubond bullets. That is better than the 300 Winchester Mag can deliver with factory ammo. I cannot understand why this is not selling circles around the other 7 MM offerings.
