If memory serves that's a low magnification scope, I have a couple around here somewhere. As long as the fine line of the duplex reticule is not too thick, you'll be fine. Sight it in at POA = POI for about 83 feet since you'll be shooting at 25 meters (if they set up normally). Some ranges (indoors) only offer 25 yards but I doubt the 6-7 additional feet would matter too much. I have shot with you at Talladega but we didn't talk much about optics. I assume you know your click adjustment increments for elevation and windage but just in case....It wears a vintage ("period correct" ) Weaver K4-1. No click (micro trac?) scope with the duplex reticle.
Progressive lenses in the classes make iron sights on a long gun more of an adventure than I think I'd want at this point.
