I would like to do the Quigley Shoot while I can still lift the Sharps. I have the Lyman 125 but don't know if it is heavy enough, 538 gr. I wonder if I need a 600 gr +/- bullet and if so what one. My range at home is 300 yards but have found a place I can go to 1200 yards with a good back stop. Finding the range and back stop is hard in Indiana.
