I've always wondered how the top shots go about setting up their rifles. So far I've gotten a nice sharp reticle at infinity, parallaxed at 23yds and zeroed at 35yds. Pellet on pellet at 35yds, and everything's going fine so far. However, I'm struggling to get a cheek piece height that will work across all three positions. At the moment i can barely get my head into position on my standers and kneelers, because its almost too high. But when I switch to prone, the cheek piece is nowhere near high enough (it's not even touching). Where am I going wrong?
