i think a 17 is to small for woodchuck, i have seen them drop where they stood, but, also, i saw one, shot it the side of the head, whose left eye came out of the scoket, dangled and he still had enough energy to make it to his hole, and make some very unpleasant sounds while dying, so i gave up on a 17 for anything other than a paper puncher, i like a good .22 for most of my small game hunting.
