There is no "chart" for your rifle/ammo combo unless you provide the speed at which the bullet is traveling. If it is Fed gold medal match ammo, it's probably doing 2650/2700fps. Once you know that, then pick an online ballistics calculator and get familiar with it. There is a wealth of info here, so get your research on, so you can find out how much you didn't know you didn't know. Welcome to The Hide.
