Brandon at AllTerra Arms demonstrates the importance of re-zeroing and re-calculating ballistics when switching between different production lots of factory ammunition. He uses Hornady Precision Hunter 7 PRC ammo in this demo, but the same concept holds true for any other ammunition type and caliber. We owe it to the game we hunt to take the time making sure our hunting rifles are set up to be as accurate as possible.
