[QUOTE="Alan Griffith, post: 706656, member: 4686"] My best friend, his friend and I are heading Montana on Thursday for a week long elk/deer hunt. They both shoot nearly identical rifles in 6.5x284 with the 140 VLD running 3050 and 3075 respectively; same powder/primer loads too. Last week, they both checked their 200 yd zeros and 300 yd impacts. These rifles are exceedingly accurate (Jon Beanland). Today, on a windless day, they were shooting at 550 yds. Shooter ap was saying 7.75 moa for the first and a skootch less for the 2nd rifle. Seems they both needed 1.5 moa more (9.25 moa) to hit @ 550 yds. On the phone I went over their Shooter rifle/load and field conditions input and we just couldn't figure out what was off. I even duplicated my buds data on my Shooter and came up the with same as theirs. In the interest of time, having run dry of N560, their powder, and a shortage of loaded ammo, any ideas on what to tweak to get things married up? Maybe tweak bc, vel or zero on the ap? For some reason my bud was using .595 bc for the 140 VLD instead of the .612 it should have been. Don't think that much diff in bc would equate to a 1.5 moa diff @ 550 yds; do you? Alan [/QUOTE]
