[QUOTE="Wingnut, post: 507500, member: 8721"] Did you just use the manufacturers numbers on velocity and BC? The program will only be correct if you use the corrected BC for your ammo out of your gun. What you want to do is zero the rifle at 100 or 200 yards which ever is the best for you. If you can reset your turret to zero at that range. Use your ballistic program to get you close at a longer range. The longer the better you can shoot. You can either shoot at the longer range and shoot for center or just shoot a group and measure the distance of the group to center. Some programs like G7's, [url=http://www.gseven.com]gseven - Home[/url], you can just input the measurement from center to save you some shooting. This will give you actuall data out of your rifle. Then the program will give you an adjusted BC for your rifle. Use this data to print a drop chart for your rifle and it will be right. [/QUOTE]
