[QUOTE="LouBoyd, post: 507628, member: 9253"] Make sure you have the correct value for the height of the centerline of your scope over the centerline of your rifle bore entered in your ballistics program. Don't guess, measure as precisely as you can. All ballistic programs have an entry for that value. It will wreck havoc if with all downrange drop calulculations the ballistic program gives if you get it wrong. It causes increasingly greater error as the range increases. Getting the atmopheric measuremets entered is importat too, but that's not very important at 300 or 600 yards unless the values in th program are way off, such as shooting at high elevations. Of course you need the correct bullet BC and muzzle velociity in the program. No ballitics program is better than the data you give it. [/QUOTE]
