Yeah, I play catapult since I was child, mostly for sparrow hunting. Still try to figure out the best aiming technique of using heaver rubber band say 7lbs, to shoot out of 25 meters. But, new equipment has made catapult hunting much easier, like what I saw the other day from video, laser aiming assistance; guided launch tube for steel shots; compound loading mechanism design....etc, accurate rage can be out 40 meters.
