Can someone explain this "internally expended energy" concept in a way that makes sense?
Seems to me that on a pass through shot, the bullet to hits the first shoulder at, for example, 2000 ft lbs of energy, half way through, it's got 1750 ft lbs of energy, and on exit it hits the far shoulder at, for example, 1500 ft lbs of energy. How is this hypothetical bullet not striking the animal harder than one that hits the first shoulder at 2000 ft lbs, half way through, it's down to 1000 ft lbs, and by the time it makes it to the second shoulder, its down to zero?
Doesn't it make more sense that, as the bullet is transversing from one side of the animal to the other, the bullet is striking each bit of flesh, bone and organ within the animal at any given nanosecond with whatever energy that bullet possesses at that time?
