so the 22 is not a perfect fit for the .68s? or maybe it was just an odd ball, could you measure the id of the 22mm please?

i know for a fact that airsoft bb's are slightly below 6mm why would paint be any different?

Paintballs diameter constantly changes with heat and moisture in the air.

What figures did you use for the QEV and do they only apply to the British QEV or the American one?

In this case I used some generic approximations based on my own experience with 3/4" piston valves as I don't have actual QEV data.

Yeah but they only apply to the piston British QEV, not the American 'phragm one I have.
