A hand operated, elastic powered catapult, including a tubular barrel carried on a hand grip and a generally conical, elastic power chamber. The open end of the power chamber is stretched around the muzzle end of the barrel and secured by a locking ring to extend back through the barrel where the closed apex may be gripped. The convex conical power chamber is composed of two conical surfaces that merge into each other a generally cylindrical projectile pocket receiving a spherical pellet. When the power chamber is stretched back and released, the pellet is projected at high velocity from the barrel.
