How to Make a High Powered Pellet Gun
Pellet guns use springs or other means to fire a projectile. You can make a pellet gun that will be able to fire a pellet for great distances by putting together a few parts from a hardware and hobby store. The pellet gun will be powered by air and so always ready to shoot. You do not need to have a lot of experience to put together a high-powered pellet gun, but adult supervision is required if the person making the pellet gun is a child.
