I've seen many opinions given regarding minimum velocity on impact to humanely dispatch big game. I believe the rule of thumb is around 2000 fps. However, the ft.lbs. of energy levels are all over the map depending on the caliber being used. Is it a fair assumption that impact energy is as important, if not more important that impact velocity? What is the rule of thumb when it comes to minimum impact energy in ft.lbs. to humanely dispatch big game?
Here are some general numbers I came up with for comparison. Impact velocities and energy levels at 1000 yards
7mm Rem Mag, 168 VLD
Velocity = 1668
Energy = 1037
.300 Ultra Mag, 180 Accubond
Velocity = 1696
Energy = 1149
.338 Ultra Mag, 250 MatchKing
Velocity = 1681
Energy = 1568
.375 Ultra Mag, 260 Accubond
Velocity = 1448
Energy = 1210
