so if you are shooting at 1000yds and it calls for 53.8 inches of elevation, that is equivalent to 5.38 inches of elevation at 100yds correct? I have in the past just shot with holdover reticles out to about 600 or so, but got a couple of guns that I want to try to take out to 1k on my farm.........not new to shooting but the long range things is a somewhat new area for me, as is turret twisting.
