Just about any quality scope mount well return within 1-2 moa. That should be close enough for game hunting, 1-2 inches at 100yds. A Picitinny rail with quality rings that have a recoil bar well normally R&R within less than 1moa.
The European dovetail mounts are indeed very accurate when R&R'ed. My ZFK changes less than .5 moa.
