[QUOTE="Buzzgun, post: 3131999, member: 4715"] Best way is to chronograph the round you will be using in the 30-30 then run a trajectory chart at [URL]http://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi[/URL] and compare the drops with your ballistic reticle. You can play around with initial sight in distance until the drops correspond with the lines on the reticle. Difficult to explain, easy to do when you understand the process. [/QUOTE]
