[QUOTE="BrentM, post: 997908, member: 61747"] I was thinking the same thing as bigngreen. Shooter can have big affect on this. Unless he holds that rifle exactly the same with similar eye alignment as well as hold to the shoulder it could affect things enough. Did you account for coriolis? I add or subtract .3 for 1000 yard shots for a 140 vld at 3020 fps. A 7 oclock is basically to your back and I aslo suspect lifting up the face of the hill he was bedded on. So, a little more speed perhaps down range, plus uphill wind which lifts the bullet a little. Besides the obvious atmosphere stuff this is something I would look at. Temp, absolute barometric pressure, coriolis, wind speed/direction and lift. What you think? [/QUOTE]
