I had the Redfield Revolution 3-9x40mm with the accu-range-reticle. I put a Redfield Battlezone 3-9x42mm w/ TAC-MOA Reticle scope on it this afternoon. Had to replace the medium Weaver rings with high rings. The Revolution was nice if I didn't make adjustments for windage. When I adjusted windage the elevation would change dramatically (like up 4" at 100yds.) The Battlezone seems to be working properly and works good so far. I am thinking that I am getting some flyers from the .17WSM ammo because out of the blue I will have a terrible shot. I also believe that right after I clean the barrel I need to shoot 5-6 rounds before I worry about point of impact. I can't be sure because I don't want to burn up to much extra ammo experimenting until I see a regular supply of it.
