All jokes aside, Red Ryders were practically made for shooting people. Low FPS. Just don’t shoot for the face. A butt shot is incredibly gratifying.
We used to play a game called “Dodge the BB” growing up. It’s a two-person game; one person gets one shot and stands stationary, the other has to run around in the backyard until the shooter shoots. Then you alternate and the initial shooter has to dodge. Loads of fun; sometimes my Dad would even join in.
