Thread: Sighting in

For a 308 trajectory with a scope mount height of 1 1/2 inches goes through line of sight at 25 climbs 2 1/2 to 3 in high at 100, peaks around 140 at 3 1/2 and goes back through line of sight at 200 yds. So a quick start can be made at 25 but it really needs verification at 200 if that is your desired zero.
