My manual (sierra) says it is between 1400-1500 ft.lbs. of energy @ 400 yrds. That being based on a close to book maximum load. 150 grn. bullet starting out @ 2800-2900 fps. More than enough for deer,moose at that distance.
Note, the manual says there is still over a 1000 ft. lbs. @ 600 yrds. given the above mentioned velocities.
