Never underestimate a Zombie. If you want to have some fun, IF you can ever find a combat shoot where they aren't to full of themselves, and will let you, enter one. It's a lot of fun and I guarantee, will make you a VERY humble person once you review how you did through the course.
Oh god, you saw my initial shooting results..I'm humbled enough! I did a lot better last night though...14 out of 20 in the black...baby steps...
