Oh by the way ,..... you want to use a longer spring to up the power ??........are you sure ?
I have a no12 hopefully on it's way, so I'll see what I'm up against when it arrives, all this short stroking is witchcraft to me, I did get some tuning advice from Jon Budd last year when I first got the rifle and he suggested getting a longer spring to help up the power, the trouble is there are so many different things that can effect power and the such and I just go by what other people who know what they are talking about, I may try a little weight in the piston first to see what that does and then muck about with the longer spring.
