I would be very impressed seeing someone make a kill shot on a live animal at 1500 yards though. Whats the flight time of a .338 at that distance? Gotta be long enough for a bear to take an unexpected step or two...resulting in a foul shot. Too many risks involved in a shot that far for me to chance wounding an animal. But would love to see someone pull it off.
Time of flight in my Edge is right at 2 seconds at 3500' elevation. As long as the animal is calm, the shot is good to go. Shot a coyote in Montana at 1732yds and he stood still long enough for the bullet to get to him and roll him. Multiple deer and elk over 1k as well. If they are amped up, or rutting bucks chasing does, it becomes a little more challenging and one has to be a little more carefull.
