Nothing cute about woodchucks. They're destructive pests. Personally, the last time I shot one was with .223 - left pieces of woodchuck where it exited and the thing still managed to get back in the hole before it died.
We chased one to the burrow, blocked off the holes, dumped kerosene in, then blew him up.
His mom asked what the thump was.
We did not tell her.
