Can you elaborate on the performance of different cartridges on the road injured deer, and where you shoot them? I have fired finishing shots on multiple elk with Lehigh penetrators in 9 and 45 Super, and not noticed much difference — meaning a shot through the brain did the job. A woman in Montana who my wife and I shoot USPSA with, says she has finished off a bunch of road injured deer with brain shots with her Glock 43.
