I have a savage 10 FCP HS rifle in 308, NF 3.5-15x50, Warne 20 moa base.

Bore sighted the rifle and at 100 yards, it shoots over 12" left of bore site. Is this normal?

Ammo is Winchester 147 grain.

The rest of the story: Had a Sightron scope on it and was shooting handloads (168 gr 46.7 gr BL-C2) and driving sub 3/4" groups at 100 yards, and doing better than reasonably well to 500 yards. Less than 500 rounds down the barrel.

Any thoughts?
