The Savage 220f love the Remington Accutips 3", also what scope mounts are you using? I love the DNZ one piece, if your right hand use part # 18200......
with the above named ammo and scope mounts I'm shooting 4" at both 50 yds and 100 yds, dead center at 150 yds, 4" low at 200 yds, and my groups at all ranges are super tight
