The ballistic chart for sighting in rifles that use Hornady bullets can be found on the Hornady website. From the home page, select the Ballistics Resource link then click the Ballistic Chart link.
Hornady offers metric and standard ballistic charts as well as a H.I.T.S. calculator to choose the most effective cartridge/bullet combinations. Ballistics charts are useful to find the velocity, trajectory and bullet weight for various guns. They are a good reference, making it easy to ensure the selected ammo is the correct choice for the firearm. Manufacturers often add new rounds to their inventories, so it is important to regularly check ballistic charts for updates.
