[QUOTE="NomadPilot, post: 333884, member: 19896"] This might help you get started. You need to chrono your load before you can hope for decent calculator estimates. [URL="http://www.federalpremium.com/resources/ballistics_application.aspx"]Federal Premium - Downloadable Ballistics Application[/URL] Then you can plug the factory data (BC, MV) into JBM's constant drop calculator. It'll tell you what range each 2 MOA equals (instead of telling you what MOA each range equals). [URL="http://www.jbmballistics.com/cgi-bin/jbmucardd-5.0.cgi"]JBM - Calculations - Trajectory μCard - Constant Drop[/URL] What I get doing it is: Zero at 200 2MOA at 390 4MOA at 539 6MOA at 665 8MOA at 773 10MOA at 868 12MOA at 952 14MOA at 1028 16MOA at 1096 18MOA at 1159 20MOA at 1217 [/QUOTE]
