My first over under pneumatic.
That long barrel? Judging by the pressure drop, the barrel should be about 8x as long as it already is. Ball valves are OK with the right length of barrel, but with such a short, low diameter barrel, a fast valve is far better.

I piston valves rock to but brass ball valve own with high pressures and they never leak. They also are just plain amazing. Also you need them to build a piston valve in most cases.
The Doors are awesome, Led Zeppelin is amazing, and Motley Crue kicks @$$.

We can often do more for other people by trying to correct our own faults than by trying to correct theirs.

Failure to plan is planning to fail.
