The translation leaves me bewildered is some areas, but I'll study it and try to see what can make of it. This rifle has much more complex internals than other PCPs I've worked on. I'm not (yet) trying to do a complete overhaul, but now I have a tutorial link, thanks to you. It should get me where I want to go and help me flatten that shot curve. How'd you find this link? I did a lot of searches, but I guess I didn't do enough!
