Need some help please ... Research purposes (Paintball crossbow)

There was an attempt over on mcb, they definitely hit problems propelling the ball just with the string, I seem to remember there was a problem with the length of the stroke using an airrow system.

Hi mate, I did product design at gcse, got an A* and wish i could have done it at A Level, my stupid sixthform dropped it when I got there , I built my own riot shield for paintball and like to keep my creative mind alive so im loving this post.
Personally I would modify the top of the crossbow so that there is a barrel instead of a grove where the arrow would normally go.
The barrel should then have a hole in the top near the back of the barrel to beable to drop a paintball in. The barrel would need a split from about 25mm/1inch from the front depending on what material you make the barrel from, im thinking of aluminium, all the way to the back so that the barrel is nearly in half. this split will allow the use of a barrel so that the paintball doesnt simply just drop out of the grove when playing, whilst you can pull the wire back behind the hole to fire.
obviously you would then need a release and lock system for the wire so when you pull the trigger the wire can fire, just use a basic latch so when you pull the trigger the latch lowers and releases the wire.

So ye basically what im saying is make a crossbow then modify it by sticking a barrel on and it should work

Using this method the crossbow will self destruct very quickly, same as if you repeatedly fire one with no bolt on it, the bolt being there provides resistance to slow the string down.

Surely the amount of resistance caused by the bolt would be negligible, as long as the wire does not collide with the part where the barrel is still joined repeatedly, then it most likely would not self destruct. To me the design suggested sounds good and I could see it working.
