The only thing I might add or subtract from what is posted here, is @ close range, shooting a thin skinned animal such as a deer with theShockwave/SST, ittends to pass thru the animal without significant expansion, usually due to the fact that is loaded so hot to achieve velocity for those long range shots. Long range shots do achieve expansion as the velocity has slowed significantly.

Conversersly if you hit a major bone on the way in at close range you will achieve expansion.

Even @ close range, either way the animal is dead, it just takes them longer to realize it and you may be doing some tracking, if you get a good blood trail.
