Too many variables to generalize. FWIW Flasc did some control bore length testing(paintball) that indicated different optimal barrel lengths for different markers Flasc Paintball!

Flasc also conducted some FSR bore diameter testing Flasc Paintball!

So .687ish and 7.5" to 10.5" depending on valve design and pressure.
