It's comforting to know I'm not the only one who likes "Small Game Hunting". I got started on this in my teens, shooting wasps in the garage. But you had to be careful, lots of breakables there! I used a pellet gun for years, often with less-than-stellar results. I remember once I took a shot at a BIG old wasp from about ten feet, problem was I forgot the pellet. Made him mad though, and he chased me all over that garage until I finally made it out the door and dove over a fence. I heard him zoom over my head as he lost track of me and kept zigzagging around the yard looking for me. Then I look up and my Mom is in the kitchen window, laughing her socks off at me. I can laugh about it now, but it was pretty embarassing for a couple weeks.
I have only rarely used shotshells, I prefer 22 hollow points at about 20-30 yards. I have a bolt-action Remington with a nice scope, and I will pour out a puddle of orange soda on a railroad tie, where there's a good backstop behind it. Then I'll sit by my living room window and wait for the little buggers to appear. It may not be sporting, but it sure is fun when you take their little heads off!
