Ok (dammit) I'll get one ordered and on the way.   It's pretty obvious that I'm gonna never be "sure" until I do.  

Appreciate the advise.  👍

I think one of those cheapies would work just fine. You need to see when to stop cranking on the hammer spring. 

 

I agree.   It's ordered and on it's way.  😊

 

I am not satisfied with my understanding of the hammer stroke adjustment.   Let's say for my current spring tension setting of 6 turns….does decreasing hammer stroke length cause the valve to stay open longer even at higher pressures, or is hammer stroke adjustments only beneficial at lower pressures (like under 2000psi) ?  

I notice that at higher pressures my gun is extremely quiet until it gets down to about 2300psi, then she starts to bark considerably louder…..but POI does not change much( if at all).     Can I tweak that change in bark by slight adjustment in hammer throw ?

 

Is that change in "bark"thee "double bounce" that I keep hearing about?  

 

 

 

My P-rod has a loud bark but you can tune down some. For the hammer throw adjustment is to find the peak FPS and then back it off a little. Now for the hammer bounce you can install 2 or 3 o-rings inside up against the valve to keep the hammer from knocking open the valve again causing wasted air. Find an o-ring that is the same size as the ID where the hammer goes. Hill airgun sells all the parts you need. LINK….https://hillairgun.com/
