So a guy either becomes dependent upon carrying a mobile device and rerunning the parameters, or he carries a DOPE book full of read-out prints and has to match up his current conditions with their respective ranges for the reticle markings.
Or a guy buys a proper ranging reticle scope with regular intervals between markings and simply has to record how his load responds at different temps and elevations, or remember a rule of thumb for temp and elevation effects.
You don't have to carry a mobile device lol We all spend enough time in the field to know the "general" weather conditions for that time of year.... Now like you stated wind will be a different animal in itself but just to the general range of the turrets with the load the shooter is using it helps. I use them down here in Florida, had a coyote pop out at 300 yards held the third hasmark at the bottom of his chest and he didn't take a single step. I sighted the rifle in during the summer that day it was 25 degrees. Just print it out and clue it to the inside of a scope cap.
