I have a scope but sighted it in a 25 yds on the first dot, 35 on the second etc. It shoots great out to 50 yds off a rest, but windage is too much at 55 yds. I too use a range finder. I had a 30 yd landmark in the right place, so putting the second dot on the doe about 5 yards beyond that worked perfectly. Its in the freezer now.
