    here are a couple ideas i wanted to share. one is a top loading hopper pump and the other is for a bottom mounted detachable magazine fed pump. trigger mechanisms are dowel pins or ball bearings depending on design. they work off the same principal as a quick change tool.

    So you want to use a push rod style sled? That will create many problems. The sled will weigh quite a bit and therefore will have a lot of momentum. Stopping it will be next to impossible. It will tear the string, draw the rubber into the barrel slots, and also eat up a lot of the shot energy.

    It might work with very low draw weights, but then the shot will be so weak that you might just as well throw the balls with your hands.
