this year, on my knight I used a Nikon buck masters 4-12x40 then I put a Nikon slug hunter on it but I haven't shot it yet, I've had a Nikon prostaff on my .300 winmag and I've used that same scope on my 870 20ga shotgun. All within the 150 range I think the slug hunter was 180 and the prostaff was 150 and the buckmaster was around the 120. I would like to try a luepold out one of these days though.
