I'd be curious to see what his gun did BEFORE he drilled the hole in it. The point being that the hole he drilled WILL affect performance. It's entirely possible that the gun had better performance BEFORE modifiation than it does after (even with the C2H2 injection).

I might actually make something like this at some point if I can get a hold of some acetylene. With a thick aluminum piston tube, a resealable injection hole, a compressed gas spring, and a chamber long enough to cause a detonation on firing, it could launch light projectiles *very* quickly.
