Quigley-Ford Custom Range Compensating Reticle - Video Demo

My only problem is we don't know what elevation & humidity the drop chart is set for. Is it correct in damp lowland Georgia or the dry, thin air at 8,000 feet in the Rockies of Montana? At 200 yards the difference may be small, but at 700 yards the difference is large enough to matter.
Quigley-Ford long range scopes...default data for trajectory calculations is 50 degrees F and 50% humidity at 3000 feet altitude for all off the shelf scopes.
Obviously for custom builts any data can be inputted for reticle etching.
