How long are these chambers? It's quit obviously not drawn to scale.

sorry the scanner must have not copied the lengths and diameter of the pipes and fittings when i changed it to jpeg form.
26"x3" air chamber
36"x1" for barrel
pressure being used on average- 40-60 psi

The GGDT results:
The energies with a 25g projectile:
40 PSI: 61 foot/lbs
60 PSI: 87 foot/lbs
.22 lr: ~100-110 foot/lbs (for reference)
Make a barrel extention, buddy... and you'd probably be better off with a 1.25" barrel. (but not by much)
