Used a Burris Sig ring set up last year for Doggin and ran out of adjustment at 1000. Had a 20 in front and a 20 in rear. I could get '0' at 100 with this. I switched to a 20 MOA base and same rings to get the 1000 yard dog this year. Problem now is I cannot get a 100 yard zero. It is like 13 inches high or so. Swapped everything back and will try again. Any ideas?
