Guys, I finally got the opportunity to get scope on muzzleloader sighted in on the new muzzleloader. I have a nikon prostaff scope with the BDC recticle. Question.......would you keep zero at 25 yards and use the first dot below zero for 100 yards? Obviously the scope is designed for bazillion yards past 100. I cannot see taking a shot beyond 100 yards here in Indiana. (at least for now) I seem to estimate better taking crosshairs upward vs downward....if that makes sense. What do you think?
