Except for arrows I simply don't worry about pass throughs...
A lung shot deer is going to die quickly and usually drop within 75 yards...
There will be blood after a few yards as they will bleed out of the nose and mouth...
Even with pass throughs sometimes the exit wound gets plugged with other matter...
Typically bullets that stay in a deer create a wider wound channel and drop the animal
faster...
If you want to drop them on the spot, go to a high shoulder or neck shot...
