RE: Hold-over or gradiated reticles?
Hold over/under suits me best.
I had a crossbow scope with one crosshair and one aiming point above & three under. It is designed for a 20 yard zero with the crosshair and the point above is for 10 yards, with the points below being 30 - 40 - 50 yards. Very accurate, but I've been shooting with a scope with one crosshair and using hold over/under for decades now. Too many times in hunting and 3-D shooting, when the pressure was on, I forgot all about the range markings and used the crosshair (and missed) [:@]
I finally got a crossbow scope with 3 crosshairs! With 3 crosshairs in the view I have to slow down and think!
Never tried a ranging type reticle on a muzzleloader scope, but I figure I would make the same mistakes, so I just stick to hold over/under and the KISS theory.
