Bob_O do you know if BC changes as speed is scrubbed off with pellets at longer ranges? In other words, a higher BC at short range calculations and a lower BC at long range calculations. Asking for the 50.15 grain JSB's @ 935-940 FPS...
I'm sure it changes.....there's an option to mess with it if you choose. I think if you validate trajectory at multiple ranges it will adjust BC but I haven't looked into it.
