a 400 yd shot is fairly easy if it is a broad side shot with any 4-10 power scope if sited in to hit 3" high at 100 yds 180 gr bullet put the cross hairs on its back maybe a 1" or 2 of daylight and your are in the heart and lungsIf a person is shooting a 180 grain projectile out of a 300 wsm rifle at 400 yards, it would have just over 2000 ft lbs of energy which is more than enough energy to take down a moose if placed in the vitals. A person would really have to know what the bullet trajectories are before taking the shot though. In this modern world, there are a few scopes out there that could accomplish this for the shooter but as previously mentioned, a lot of moose are shot a lot closer than further.
