I'm loading 77gr SMKs in my 20" AR, with a velocity around 2750fps at the muzzle. My goal is to use an optic that will get me to 500 yards within one revolution of the elevation turret, and I am looking at a couple of different scopes.
The scopes I am considering are a Burris Fullfield II Tactical 2-7x35, which has 1/2" clicks and the Ballistic Plex reticle, and a Nikon Monarch 4-16x42SF with mil dot and 1/4" clicks. Now, if I am reading the ballistic calculator correctly (using 2750fps, BC of .350, 100yd zero, and 2.5" scope height using a LaRue SPR 1.5), I will be 60.2" low at 500 yards requiring 23 clicks up with the Burris and 46 with the Nikon.
The Burris shows 24 MOA for one revolution, whereas the Nikon shows 12 MOA per revolution. Correct me if I am wrong, but it seems like one full rotation on the Nikon will get me to 500, while 1/2 turn should do with the Burris. Am I reading this correctly? If so, theoretically I should be able to get to just over 700 yards in one revolution with the Burris. Am I missing anything here?
