This is defiantly not big game hunting but it was very, very lucky and kind of cool. So today I decide to shoot my really expensive pellet gun. I use this gun for the crows, black squirrels, and other pests. Since it is the spring now and the pests came out I decided to sight it in. I shoot 5 shots and do minor changes to the scope. All of the sudden I see a robin about 100 yards away from my window, (witch is where I am shooting from.) I quickly make adjustments. I make the scope higher and more to the left. I take my aim and I breath in and hold it. I squeeze the trigger. The bird is down. When I went to see the bird I just happened to hit it in the head! This was out of pure luck, maybe some skill involved.
