: I've started work on my new CO2 powered cannon. I have completed building my valve. It is desinged to use CO2 without a regulator. I'm haveing trouble with some of the seals, but I have gotten off a couple of shots with my new nerf round chronoed at 220 fps. I intend to put in a Tippmann type velocity adjusting screw so I can chrono down to 200 fps or less depending on field rules. Out of curiousity, how close did it's performance match the predictions by the sim? : The whole cannon looks like a shotgun and is under 40" long. It is pump action and can be fired every 5 seconds. : The only PVC on it is the barrel. The valve/expansion chamber is alluminum. and the stock is wood. : I expect to get more than 5 shots per ounce of CO2. : Hopefully it will be ready for D-day in OK.
