Out of 14 mule deer, I've only had one run off...a doe shot at 80 yards from above that destroyed the lungs. Ran off about 30 yards and I tracked it to where it lay dead. All others lay where they were hit, only about 4 or 5 were instantly killed. This, at ranges from over 300 yards to 60.
I use a 30-06 with Hornady 165 gr BTSP, medium load of IMR 4350.
God and soldiers, we adore
In times of danger, not before
With the danger safely righted
God is forgotten, and soldiers slighted
