KE is simply the measurement of energy. The term itself won't kill anything. A bullet can kill without any blood loss. Its a combination of things that do the job. Velocity, frontal area, ME and shock all contribute. Part of the problem is getting lost in the terms. Shock forcing blood back to the heart or brain is part of it. I saw some good testing that showed that when a bullet strikes when the heart valve is open, death comes almost insatntly. To fast to be just blood loss. Wide Meplases send shock waves ahead of the bullet creating a larger wound channel. I am no expert but I have studied this quite a bit. Opinions very and hard proof is hard to come by. However with an open mind, some things start to make sense.
