I just received a heavy hammer spring from Talontunes yesterday and did some preliminary work over the Chrony before it got dark. Wow! 1st, I can pressurize to 3000 PSI and effectively use the additional 300 PSI. With th lighter spring, I could only pressurize to 2600 if I wanted a shot string that would hit same POI. 2nd, the spring gives me an additional 100 or so FPS on some loads which really drives up the FPE. That said, my Sumo will not cut it and I will have to buy a Ronin to quiet it up if I keep it configured this way. Additionally, the power wheel doesn't do much for you with the heavy spring.
Today, even though it is raining, I am going to try shooting with an oring under the top hat on the valve and see if it does anything. I can't use the Chrony but I'll see if there is a noticeable report change.
