That's what I was wandering was if the adjustment screw would eventually just thread out the end. Thank you
At least from mine, will likely adjust until the rifle won't cock (striker won't move back far enough to catch the sear) before you run out of threads.As you know, it's not the ideal way to tune a PCP.
I think you have about 10-12 turns worth of adjustment from bottom(minimum tension). If you max it out, it won't bottom, rather it will come out of the threads and you will feel the screw "hopping" on the threads and not moving anymore. Obviously, you don't want it that far out, and you want a few threads to be engaged.I'm assuming you inserted something in the hole in the hammer while adjusting the tension, otherwise you'd just be spinning the hammer around. Without knowing if the gun has been modded at all, I can only give generalizations. There is a law of diminishing returns on that spring adjustment though. I'm thinking you'll get more than one magazine even at maximum power if the gun is stock, and your sweet spot will likely be in the 9-7 turn range from minimum spring tension. You can may be able to get more power with more turns, but the higher you go, the closer you'll be to a steadily descending velocity instead of a usable shot curve.If you give us more info on the gun and what specifically you're wanting to achieve, then the folks on here are sure to have some very specific advice/tips for ya
My guess is that if you actually turned the preload out 8 turns (ie you had the hammer pinned so you were actually adjusting the preload, not just spinning the hammer around).... you have created an air hog with almost any weight of pellet except possibly EunJins or JSB Heavies.... Past a certain preload, with a given pellet, you won't gain more velocity, you will just waste air, because the pellet has left the muzzle before the valve closes.... Heavy pellets, moving slower, delay that, so can stand more preload....Bob
