Take the guesswork out of the game with this 3-10 x 40mm Powderhorn Muzzleloader Scope. It's outfitted with true ballistic marks on the reticle to indicate 100-, 150-, 200- and 250-yard points of impact. These marks are based on a 150-grain powder charge combined with a 250-grain bullet to let you know exactly where to hold based on the range to the target that you've determined. This Scope Kit includes a set of Cabela's Muzzleloader Integral Rings and Bases.
