Even though I haven't shot a woodchuck in probably 30 years, I'm still enjoying this thread.
I used to shoot them a lot as a kid. My favorite was with my .44 Redhawk.
One year, we had a tornato go through. It tipped over trees, silage wagons, sheds, you name it.
We had a neighbor with a sizable population of woodchucks out in his pasture, so I wandered over to ask permission to hunt.
He says "Sure, you can hunt the pasture, but I got a ton of them right here behind the barn I'd like to get rid of."
I'd walk around the tipped over wagons and whatnot and shoot them with that .44 from probably anywhere from 10 to 30 yards.
I always thought that farmer had to be half nuts to let a 17 year old kid with a cannon shoot that close to the farmyard.
Sure enjoyed it though.
