l put a nikon omega on mine. But if i was doing it again i would just put a nikon prostaff on it and sight it a little high at 100yds and it would be good for as far as i would ever shoot. I would run about 50 strokes of jb bore past thru it before you shoot it. Mine loves just about anything stuffed in a harvester short black sabot. Ive been shooting the Hornady ftp 250g bought in bulk $25 for 50 just to pratice with and the barnes 250g tez to hunt with, both in a harvester short black sabot. They shoot excatly the same in my gun............ you will love it , they are tack drivers
