Pretty neat - and I mean that literally, that primer work is impeccable.

Have you any idea of muzzle velocity or range?

Thanks guys, i'm not sure how far i can shoot something yet but i can say that when i added the 8 foot barrel to it theres a huge difference in performance. In the video i have the 6 foot barrel on... Whats amazing is how quiet it is, with both barrels. I dont even need a silencer.

I really like this gun. Very nice layout - especially the minor details, such as the handle attachment system, the barrel support system, the corrugated tubing over the wires, and the manner in which everything is tucked away, with minimal clutter visible.

GGDT says that with the 8 foot barrel, this launcher should have a muzzle velocity of ~440fps and a muzzle energy of ~360ft/lbs with a 55 gram potato slug. Quite impressive for a relatively small launcher.

Why GGDT over EVBEC? I know EVBEC makes some assumptions, but I'd be more confident of a good result from it for this than using GGDT.

GGDT and EVBEC are velocity predictors, not people.

GGDT = Gas Gun Design Tool - used for pneumatics
EVBEC= Energy and Volume Based Estimator for Combustions.

Both are linked with the Spud Wiki, under "Computer Applications" (link should be on the main page).

Both programs seem to produce virtually identical velocity/energy figures when all variables are inputed correctly, but it is just a matter of preference to use GGDT.

Dude, wangpushup can you PLEASE tell me where you got that type of regulator from? I've been looking all over the net and I can't find something like that. Can you or anyone refer me to a site where I can order one?

Thats a sick cannon and very well constructed, i like it alot.
thanks
