I used to shoot grasshoppers with my Red Ryder. The Red Ryder is still made, but they've continually nerfed it over the years. Mine could only pierce a Coke can, and then only one side of it. It failed to kill the one bird I shot in the head with it (it was fine; it flew off. I'd have been fine with it being dead, though). It was insanely accurate, though. I knew what rear sight setting I needed based on distance to target and could hit where I wanted every time. Newer Red Ryders are basically glorified airsoft guns.
Note regarding that bird: It was a mockingbird that squawked on our chimney every morning at 8 AM, echoing through the whole house and being incredibly obnoxious. It was impossible to watch TV or do much of anything in the family room when it was around. I'm glad I didn't kill it and that it didn't come back, but I'd simply had enough. I had to arc the shot in from probably 50 feet away, and it was an incredibly good shot. The shot hit the bird square in the head and knocked him off the chimney. I got up on the roof and verified he was gone.
