[QUOTE="bill123, post: 1081458, member: 69116"] First off, I think that you would end up with a more precise drop chart if you calibrated your program shooting groups at dots on paper from a solid rest instead of single rounds at animals and trees. You haven't told us what level of precision that you, your rifle/ ammo combination are regularly capable of. Narrow that variable down first so you know that the error is solely related to the ballistic app. I'm not familiar with isnipe but a good ballistic calculator should have a "truing" feature so you don't have to randomly adjust velocity. Maybe isnipe has one and you were using it. I couldn't tell from your post. If it has one and you are certain that the error is not shooter, equipment related, this should be a simple fix. Keep us posted [/QUOTE]
