I realize this is an old post, but I'm gonna respond anyway. My Dad put one of these on a Marlin 17 HMR. He swapped it for a Bushnell 5-15 Legend he wanted on another rifle. The Cabela's Pine Ridge got pulled off and returned after 1 weekend of trying to use it on prairie dogs. The clarity was awful. The adjustments seemed to work alright, as there weren't any problems getting it zeroed. I can't say wether the yardadge markings were correct or not(for the trajectory compensation), since we zeroed it @ 100 yards and then took it out after prairie dogs. As far as the clarity, it got blurry around the edge of the scope and had kind of an amber tint to the lens. I don't think the amber tint would've been so bad if the resolution was better. All in all, my Dad loves using his 17 HMR on prairie dogs, but would rather not have a scope on it and not be able to use the gun, than have this scope on it! HTH!
