I have a Savage 110, the first shot is not bad, however, each shot after that wonders as the barrel heats up. I am bench resting. After 6 rounds I can adjust the scope and bring it back in. Is this common? Is it the scope or the gun? I really do not have confidence in the weapon to know the important first shot is going to hit where I'm pointing. I never had this issue with my Remington 760.
