Buy a box of premium 180gr ammo, shoot half of it at the range sighting in and practicing first-shot hits within 1" of your aimpoint at 200 yds, then keep the other half of the box for hunting for the next several seasons, firing two rounds at the beginning of each season to reconfirm sighting. Or, you could get into reloading, but your ammo would cost you twice as much and you wouldn't have any free time. LOL.
