As an example, let's take a .30-30 rifle firing a Federal factory load with a 150 grain bullet at a muzzle velocity of 2,390 fps. At the muzzle that bullet carries 1,900 ft. lbs. of energy. At 100 yards the energy has fallen to 1,355 ft. lbs. At 200 yards the energy is down to 945 ft. lbs. At 300 yards the energy has fallen to only 650 ft. lbs., which is below our 800 ft. lb. minimum. The velocity, by the way, is down to 1400 fps at 300 yards. One could conclude that the .30-30 is about a 200+ yard deer cartridge, based on its energy, and one would be right.
