[QUOTE="Greyfox, post: 1472122, member: 10291"] Your BC adjustment seems high and indicates there may be something else going on. The Bergers are generally quite close, as is the velocity reading from the Magnetospeed. Any BC adjustments I have made with the Bergers have been at most, 20% of yours. The few times that ai have seen this issue, ruling out equipment, rifle support,etc, it turned out to be either an incorrect zero, or incorrect atmospheric conditions. At 100/200 yard zero’s, parallax setting can get tricky. I double check my settings at 100 and 200 yards...and make sure they are “precise”. Sometimes the local reports for pressure work fine, most times the do not match my Kestrel or my Ballistic RF. Just some thoughts. [/QUOTE]
