I just discovered the Spudgun at TheScreensavers, which I haven't been able to watch for quite some time now. Thanks to SuranWrap for posting the link to "Unscrewed with Martin Sargent". Posting this in the thread he'd created would have been off-topic so I figured I'd create my own specifically related to the Spudgun.

Specs:
- o Twin 6" x 36" sch 40 chambers. (2035 cu. in.)
o Dual Supah-Valves.
o 8' long, 3" dia. sch 80 barrel.
o Ported muzzle break.
o Breech loadable.
o 9' 6" overall length.
o 70 lbs. total weight.
o Massive recoil!!
o Primary "ammo" -- 20 and 24 oz. plastic soda bottles.
o Muzzle velosity -- Forgot to bring my chrono along....sorry.
Have fun.
