[QUOTE="Tumbleweed, post: 1076896, member: 9281"] Ok, here's some specific drop info so everyone understands what I'm talking about. Atmospheric conditions are pretty consistent this time of year. Temps around 65, air pressure between 29.95 and 30.30 and humidity between 50 to 70%. 300 RUM 230 Berger at 3,240 fps: Zero at 100 yards, bullets all touch 300 yards, shooter calls for 2.4, dialed 2.5, fired two shots with perfect elevation and less than .25 MOA vertical. 556 yards, shooter calls for 7.4, dialed 7.5, fired two shots with less than .25 MOA vertical and pair center averages .75 MOA low. 777 yards, shooter calls for 12.6, dialed 12.7, fired two shots with less than .25 MOA vertical and pair averages .25 MOA high. 1000 yards, shooter calls for 18.8, dialed 18.7, fired two shots with less than .25 MOA vertical and pair averages 1.5 MOA low! I stopped here as there is obviously an issue. 300 H&H 215 Berger at 2,670 fps: Zero at 200 yards (as best as I could with a still unstable bullet) 375 yards, shooter calls for 4.5, dialed 4.5, fired two shots with no vertical spread and and shots were less than .25 MOA low. 551 yards, shooter calls for 10.0, dialed 10.0, fired two shots with a vertical spread of .6 MOA and pair averages .8 MOA low. 700 yards, shooter calls for 15.3, dialed 15.5, fired two shots with less than .25 MOA vertical spread and pair averages 1.25 MOA high!
