RE: knockdown power... fact or myth?
A very interesting link. I did not read it all but saved it to study later. Many hunters base their opinions on the "performance" or a cartridge or bullet on a small number of experiences with it. "I once shot a deer with a "X"and it fell dead right away"! or "I saw a fellow shoot an elk through the heart with an "X" and it ran away andwe never got it".
There are so many factors about 1. the condition and state of mind of the animal. 2.The the angle and location of the bullet entering and traveling in the animal. 3. The construction of the bullet, its velocity and how it acts in the animal.
I think we have to define what we mean by "knock down power" before we can say flat out it is a mith.
