Of course the permanent wound channel is larger than the expanded bullet and you are very correct that it is much larger at the beginning of the wound tract where the projectile was travelling at higher velocity. This is the result of hydraulic shock. The bullet moving through tissue displaces the tissue and more importantly the fliud in that tissue and actually sends it outward from the bullets path much like when you throw a rock in a lake. The faster the bullet is moving and the more rapidly the tissue and liquid is displaced, the greater the distance that damage is done away from the bullet. Basically, the tissue cannot contain the fluid. Some is permanent damage/permanent wound channel and some is temporary/temporary wound channel. Both channels vary in size frome larger in diameter upon impact to smaller as the bullet slows.
Energy definitly played a role in that it kept the bullet moving forward and pushing this hydraulic wave outward from it. It allowed the bullet to do its work.
