I am very new to muzzleloading and have a question about sighting in my scope to shoot 100 yds. I have a TC Encore with a Nikon ProStaff shooting 100 gr Triple 7 and pushing a 250gr SW super glide. I am getting good groups of three (allwithin an inch diameter)about 2-2.5 inches abouve the bull at 50 yrds. Can anyone tell me were the POA mightbe at 100 yds?
