Deer are tough creatures..
Yesterday, while bullet testing and meat hunting I shot two deer both about 90 pounders. Both shot at approximately 100 yards with a 308 loaded with Nosler accubonds. Both deer were double lung and heart shot breaking the off side shoulder. They both bucked up and stumbled then ran all out for another 100 yards. The wound channel was large as my fist. Both leaked like a bucket with a quarter sized hole in the bottom and 20 psi on the top. Yes, I could have head or spine shot them and planted them in their tracks. This experiment just went to prove you can double lung, heart and break the off shoulder, and a deer can run another 100 yards. Both of these deer were dead on their feet.
