As far as accuracy goes, I would try to find a better round/load to get what you are talking about for the longer distances. As far as no expansion, I hear what your saying, but in reality, you can't base it on what that the exit hole is somewhat larger than the entrance.
You get what is termed as the tear factor upon the round traveling through a media, here it is elk tissue, and the kenetic energy is transfered through the round, destroying everything in a funnel shape pattern. Projectile mushrooms as designed, stays intact, exits. Vitals area and surrounding tissue are destroyed, massive blood loss and shock insue.
I just shot a whitetail buck this past Il gun season facing me with a .460 pistol shooting a 225grn Flex Tip at 60yds. The round destroyed 5" of brisket, turned the lungs into water, and blew 4 ribs apart diagonally upon exit, leaving only a hole the size of the tip of my thumb. Buck died in its tracks before his knees buckeled.
