Why do they use a long rod? Because then the projectile is launched without pressure having to build up again in the barrel wich could cause it to explode. Imagine an egg in a big shot. The egg would stay intact when launched from the seating of the sling. If there would be space between the egg and the seating when the sling is launched, the egg would explode when the seating would hit it at high speed. I can imagine that happening here too...The kinetic energy in this last case would be much greater than it would be when there's no spacing between projectile and sling. Without space it would gradually build up, instead of very sudden....
THe wooden rod could split open too, and therefore wedge the rod in the barrel so it gets stuck. Pressure needs to go somewhere though...
I'd think of a hollow aluminum pipe here wich is welded shut on the base-ball end.
Be careful, because I don't wanna see you die... You're playing with pressures up to 5000 times atmospheric pressure here... Don't really know if I used the proper words or sentences for this here. Sorry for that.
I'd love to see this though...
