Hey guys, i just bought a Hatsan Vectis in 22 cal, and i want to do some hammer spring adjustment, but the problem is that i don't have a chrony to measure the fps. I can't buy one right now so i wanted to ask: how many turns would be okay to do to increase the fps to the maximum possible?

In my experience, accuracy is much more important than absolute speed. I suggest you shoot it and get to know it before you "improve" it.

Thanks for the advice, i want to improve the fps cause i ordered some nsa 17 grain slugs, and i'm pretty sure that will shoot those to 870-890 fps, and i wonder if adjusting the hammer spring will shoot closer to the 900 fps.
I already shot more than 500 shots with different slugs and pellets, and with the jsb hades i get less than an inch groups at 30 yards, wich is the farthest i can shoot in my yard
