What bullet weight and powder charge r you using? Does the BDC reticle work right for u? I was using Hornady 250gr SST bullets. But when I went to the new Leupold scope. I went up to the Hornady 290 gr Bore Driver bullet. Both bullets I have been shooting 84 grs of blackhorn by weight. My muzzle loader is a CVA Optima V2 50 cal Long Range rifle.
