i looked at ordering a new scope from leupold with laser engraving, my name, etc.... when i got to the custom turret, it gave general bullet, velocity, alt., etc.. questions... now if i go with getting a turret for an existing scope with yardabe markings, should i shoot the ranges, and record the actual drop at each ?? if so just how big of a target do i need to aim at and record the drop at 1k ?? this just doesn't seem reasonable..... does this work for a yardage turret, to shoot it useing clicks, and tell them, and then be able to get the yardage turret based on clicks ? to me it seems easier to put yardage on a turret and just turn it past a few clicks and then back to the actual, then to have to count clicks.
