Ok GGDT Was pretty close with this gun. GGDT quoted the FPS @ 812. I Chronographed an average velocity of 785-793 FPS. Now thats more like it. Although 800 FPS would be nice. I will need to get the chamber to a higher pressure.

That puts 1/2" SDR 13.5 at a better fit with .69 ID doesn't it now?

This guy who owns a machine shop saw my guns and said I could go in and weld steel cannons for free and stuff, I'll bring in my paintball gun barrel and see about machining threads for a paintball gun on PVC.

38 inches is the longest piece of SDR 13.5 I could get without it bending, so guess how long my paintball gun barrel will be if I can put threads on. :D
