I know of a fellow Game Warden who took a call for an injured deer along I-80 in our home county. He found the deer along the roadway and it was struggling to get up. It was absolutely pouring down rain so he didn't want to get out of the truck. Put on his emergency lights, hit the button for the passenger window, and touched off a round to put the deer down, from the driver's seat. Our duty weapon at that time was a 4" Smith 686 .357 magnum with 145gr. Silvertips. The blast and shock wave scrambled him so badly he could barely get off the road. He couldn't hear anything, couldn't focus, and was not feeling well when a state trooper stopped to see what was going on. Needless to say, there were memos a flying from the Regional Office!
