I've lost 3-5 deer over the 25 years that I have been bowhunting.You hunt long enough and hit enough deer it is bound to happen.I have also missed a few over the years and I can tell you one thing you will agonize more over a hit deer that is not recovered more than you will a clean miss.It really tears me up tp hit a deer and not make a speedy recovery.Couple of the deer I did find ,but a little too late.I keep hearing about the anti's looking for stuff to use against us on hear,but what about all the deer you see laying along the side of the road after being hit by a car,man what a wasteand thats just the ones that don't make it off the road to die.
