Please call Hornady at 1-800-338-3220 for ballistics information. This is for the .308 160 grain FTX bullet. When I brought up this bullet's ballistics, I got the preceding message. I would think that you could use 160 - 165 grain data out of a reloading manual. I seriously doubt if you would be able to match factory loads for velocity. When ever a manufacturer brings out specialty ammo, they usually have developed a "secrete powder" to move it's performance ahead of any thing you can handload. Good Luck and Good Shooting
