So I finally caught a day when it wasn't raining and the range wasn't flooded and took out my T/C .54 cal. Put up a target at 50 yds and couldn't hit it. Put paper all around it to see where ball was hitting and found it to be hitting about a foot high. I went to adjust the rear sight down and found it to be all the way down on the barrel. I started with 60 gr of Pyrodex weighed. Started dropping powder amount until I was down below about 45 gr. Made no difference. Still hitting high and began to produce a really bad group. The front sight is already about a 1/2" high and anything higher would look crazy. Any suggestions as to how bring this group down and if I need a new set of sights what would you suggest?
