Craig,
Even standard velocity LR .22 will almost always leave a bushy tail high up on a tree branch, where a short will almost always knock his little ass right off the branch, and save you a hour of rock throwing. .22 short out of a Remington 552 is way more than accurate enough for that type of work.

Believe me, finding water in the woods, and proceeding with the evil job of deskunking out there keeps everyone in the neighborhood, not to mention the house you share, much happier. The second bath can follow at home. It is far less evil if the first coat of skunk juice has been removed out there.
The skunk kit has a very good pair of rubber gloves in it.

Best,
Ted
