Squirrel and coons? Yeah probably overkill. Plus you really, really dont want to send a 223 round up in the air. You shouldn't do it with a 22lr either, but you could still use a branch as a backstop with a 22.

I was assuming you already had a 22lr? If not, everyone needs a 22.Don't get cute with the caliber, get a plain old 22 first, then if you want another rimfire you can consider something different.
