On a given shot placement, a pass thru, and a full blast thru will deliver more energy every time than a non-pass thru.

Maybe I missed something here.The statement doesn't appear to consider all variables when talking expansion,retained energy,bullet config,etc..etc..
vs a "Pass Thru". Based on my own field experiance PT does not always mean more expended energy into the Kill Zone/Vitals vs retained bullet.

On Deer sized game using 12g slug slinger - I've always gone for the slug that goes in expands into vitals and leaves a dimple just under the hide opposite side - animal drops within XX yards.That is the perfect projectile.
BTW I'm talking 100-125 yrd shots.

I have never found any advantage in "pass thru" other than a blood trail that you might have to follow for XXXX yards to find animal.
