Scope base.
They make scope bases with preset MILs or MOAs built in, so the scope can be used at longer ranges without running out of turret adjustment.
The scope on my .308, for instance, is mounted with a 20-MOA base to allow me to reach out to 1,000 yards (one of these days). The first 20 MOA of adjustment is "built in"
That's what solves the problem of scope view versus muzzle inclination for long ranges.
Gotcha - thanks. Shoulda thought of that........
So a scope set for 1 mile away would be way off for 100 yds........100 yd. target might not even be in the field of view........
