RE: 4 dead deer none recovered
A single lunged deer can travel well over 10 miles and generally does.
A large percentage of one lunged deer survive.
I had seen plenty of deer one lunged and walking about within the week.
I have also seen lots of kills where the scaring on the lung is very visible and the cause obvious.
This year I have seen three deer that were one lunged and then taken within two weeks after the fact during cull hunts.
