Ok. I'll see what I can preload with. I really wasn't impressed with my polish job on the striker, so this would be a perfect opportunity to redo it. And toss some 30 weight at it. Have to double check the poly tube. During my search, I saw where a stock trigger spring was used in the valve. Does this sound about right?
David, do you, or are you experiencing any issues when cocking it? When I pull the handle back, sometimes it sets, sometimes it takes a few pulls to get it to lock the hammer back. I fear if I install a stiffer spring, I'll never get it to cock right.
