in the upcoming presidential election, there will be several candidates who will be running, one of whom is Hillary Clinton. Now WAIT A SECOND!!! I though there was some sort of rule that prevented someone from serving more than two terms in office. Vote Against Hillary: Presidential Elections 08

I calculated the barrel to chamber size at 100psi and i use a quick fill co2 changer for paintball right into my resovoir. It fills a 10" long 2.5" wide cahmber to ~100psi. It then boes to a modded sprinkler valve and then to my barrel. It does work tho, i can shoot potatoes about 200 yards sometimes more. these co2 do have alot of pressure and if your potato doesnt get shot and pressure builds the whole thing could go boom

Try a grammer lesson man... That post seriously made me feel like I was on drugs when I read it...

Your chamber has about 49 cubic inches of volume... So a 12 gram co2 should fill it to about 90 psi according to http://www.spudfiles.com/spud_wiki/inde ... _cartridge

just slam it down, and this little sherp thing piercxes the co2 cartridge,
and frogy, it has a vent theng that if you get over 70 psi it lets out all the air.

So is it one Co2 cylinder for one shot? That could be expensive.
