Brilliant, cheers guys. So at 200 yards a drop of 50 inches equates to about 25 MOA of adjustment I need to make? My scope should be able to do that. I know its asking a lot taking it out to 200 meters/yards, but I love shooting my M&P 15-22 so i'll take it along anyway and give it a try. I'll let you know how i get on. Thanks again.
