[QUOTE="entoptics, post: 1902121, member: 104268"] Took the time to do a little math for you using [URL='http://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi']JBM Ballistics[/URL]. Used conditions typical of where I shoot/hunt most (2300', 50°). Warmer, higher = less shift, colder, lower = more shift. Generic 30-06 With 178 gr ELD-X. 50 fps ES. 2775 fps = 21.2" drop @ 400 yds, 72" @ 600 yds, 161" @ 800 yds, 301" @ 1000 yds. 2825 fps = 20.3" drop @ 400 yds, 69" @ 600 yds, 154" @ 800 yds, 288" @ 1000 yds. So for 50 fps ES, that's roughly 1/4 MOA @ 400, 0.5 MOA @ 600, 1 MOA @ 800, and 1.25 MOA @ 1000 yds. [/QUOTE]
