if you ever pull the trigger on one of those, you'll understand why it does that much damage.

With the extended barrel, you can wring over 3,000 fps from the muzzle with a 750 grain bullet. Anyone care to do the math to find the foot pounds at the muzzle?

Lessee, 750 x 3,000 x 3000 /450240 (the gravitational constant)yields about 15,000 ft lbs.

Compared to the standard 30-06 load of 150 grains at 3,000 fps

150 x 3,000 x 3,000 /450240
yields about 3,000 ft lbs.

Gravitational Constant: 1 lb (454 grams) at 31.5 fps/sec
