Holy crap dewd, You just triple posted! :shock:
It's recommended to edit rather than do that.

Anyway to check your velocity download GGDT and look at that.
Burst discs are like the most simple valve, look in search or wiki.
As for filling, if your hooking up to a compressor, a quick connect is prefered over a shrader.

Geez, atleast your enthusiastic!!! Keep us updated on your progress! 8)

You won't be able to break the sound barrier with this unless you use dangerously high pressure (probably over the burst pressure of the pipe), but you should be able to fire heavy rounds with a lot of energy. I still say at least 50 feet of barrel length, or more.

As to most powerful on the site: NO. Not even close. _Fnord's BGP had a 40' barrel and a gigantic chamber. That's not even counting SWAT and SCTBDCv2.0, both of which are far, far more powerful than this could be.

AGREED- This is just going to be a really big gun with normal pressure.... I beleive the Dubya could overpower it hands down ( SWAT and SCTBDCv2.0 would blow past this without even concideration)

But still, It might be one of the longest guns on the site :D

Don't use 330 PSI with a gun made out of PVC, stick with 125 or below. PVC has dangerous failure characteristics, so you should use caution with it.
