Centering and Aiming

I've always been terrified of guns. But my nephew Scott received a pellet air-gun as a gift after completing a gun safety class with his dad. They live out in the country with a huge chunk of wilderness behind their house. They set up a target of three orange metal circles on the edge of the woods and invited me to try my hand at shooting. It took me a while to line up the gun's red light in between the two green lights and then aim at the orange metal disc. The gun was heavy. When I lined everything up I pulled the trigger. The blast was so loud, I jumped through my skin. Then I heard a clink sound. My pellet hit the orange circle! It took me 45 minutes to calm down. I loved it, way too much.
