GGDT Optimizations?

Unread postAuthor: blackosprey » Sun Feb 17, 2008 8:02 pm

Hey I'm making a marble/AA battery/nerf dart gun, and was wondering if someone could check out my GGDT file for me, as I'm not sure if what I've got it optimized to is actually good or not.

Some specs for you:

Barrel: .5"
Chamber: 2"
Total Gun length: 50"
Calculated Barrel Length: 45.71"
Calculated Chamber Length: 54.29
Valve: Orbit Watermaster 1"
Pilot: Blowgun


By the way, it would be nice if someone could help me out with the valve flow coefficient; I pretty much left it alone.
