Yea, unless you get a preset pressure there is no way to know output w/o a gauge downstream.With the monster weight factory hammer would go a tad higher in pressure @ 1.8 to 1.9K Lighter hammer and lighter poppet/hammer springs will allow much more effective use of lower reg pressure in the 1.5 / 1.6K rangeSadly it comes down to balancing the system air storage to pellet and your going to need some fiddle time.
i leave the pump connected when i am testing pressures. it is a little awkward at the bench, buy gives good readings the whole way.
In a .177 cal rifle you really do not need too adhere to the 1 cc per Ft lb plenum volume guideline.
Got things apart and measured this morning. Here is what I haveI.D. of reservoir-----1.035I.D. of transfer port-----.113I.D. of port in breech-----.115I.D. of discharge port in valve----.110I.D of inlet port in valve----.250My calculations for fill available were done as follows:Overall length of reservoir to valve-----14.87514.875 x 1.035 = 205.084 ccdeduct cc lost by end cap space taken 4.24cc201.6 available ccSpace consumed by regulator----25.84cc201.6 - 25.84 =175.7620cc standoff (1/16th wall thickness) 1.035-.125=.910 .455 radius @ 20cc = 1.875 long standoff1.875 standoff (1.035 diameter) deducted from 175.76-25.51 = 150.25ccSound right??
