ryncam I got a Burris Fullfield II early last year for my .270 and liked it so much that I bought another for my 300 WM. Both scopes have the ballistic plex reticle and depending on the chambering you're putting it on determines your sighting in at 100 yds. I shot the rifles alot last year at various distances andused them on an antelope/mulie combo hunt last year and the reticle works as advertised. The antelope was taken at 275 yds and the mulie at a range I won't say here cause some people will think I'm lying but I have a guide that did the ranging with his Lieca rangefinder and witnessed the shot. But I practiced, practiced and practiced all summer.
