65 yards 2 feet, 7 inches
Wrong ....Thats 65 yards 2 feet 9 1/2 inches ......get it right man ....lol
If I were you, I'd not do your initial sight-in at 100yards.
Start at 50...Heck, start at 25 and then dial-in at 100.
As said above, at 50 yards, 1" high is a very good starting point.
Sighting in at 100yds might be a lesson in futility.
