I own a Knight DISC rifle, topped with a Leupold 3.5X10X40 Vari-X III. I usually shoot Barnes 250 grain Redhot saboted bullets, in front of two 50 grain pyrodex pellets. While I can shoot 2 inch groups zeroed at 100 yards, I've never tried any shots beyond 125 yards. Any long range BP hunters out there? Where could I find trajectory (bullet drop) tables for this combination??
