[QUOTE="Broz, post: 652714, member: 7503"] Jason, I have never needed multiple BC's until I got past 1200 yards. And not with all rifles or bullets. I have seen some go 1500 plus with one G7 BC. I dont know what was going wrong with your BC from the program but that is huge. I say it is wrong and the factory BC would be closer. I use BC to FINE tune, and velocity to get on path. Most times a velocity adjustment alone will get it done. Also if you had the majority of your hits with in 4" at 800 yards that is probably as good as in obtainable. A rifle, ammo and shooter holding 1/2 moa at 800 yards is a good team. 1/2 moa is 4". My advice for anyone is to use the factory BC or a Litz BC and adjust velocity untill you go past 1000 or 1200. The more actual dial ups you have from different distances you shot and recorded the better you will be able to fine tune. but always remember the 1/2 moa accuracy of the team (rifle, ammo, shooter skill) 1/2 moa groups are golden, use the center of the group for the reference point to get the needed dial up.
