And too many folks rely on deer dropping at the shot... if I were them, I'd learn to track as best I could. Sooner or later even with the 50 loudenboomerDLA express magnum you are going to have a deer run. They all run if you miss. If you hit they run less....
If a deer drops in it's tracks, it's because you hit it in the CNS, other wise, it's going to run....at least a ways.
