Well, I guess Google has proved me wrong once again. I went shooting tonight at dusk and the cannon was working really well. I had to glue in my protective cap that isolates the handle with the electronics from the combustion chamber. Now that I eliminated that source of pressure loss we get a consistent 200 yards out of it :D

Me too! I've been lusting after one of those clear PVC ones for a long time now...

Oh and a cool thing I found out, even though the barrel PVC is white, at night it glows bright orange during the launch. I never noticed that during the day...wish I could capture it on film.
