As posted by me previously, I have a nice original sporting roller that I had thought about converting to cf. Most folks here said to leave it be and shoot it with 44rf cases from DGW. So, I got cases, 22 primer shells, round balls correctly sized for bore diameter and some 3f black. Went to friends place in Maine, put target at fifty yds. Sights were difficult to pick up, the day was bright sun, no wind. Five shots were all over the target, friend tried, same result. Moved target closer, about twenty five yards, best group was four inches. We both agreed the sights were too fine, the rear aperture is too small, as is the front bead. Chambering, extraction, set trigger operation were all excellent. Plus, shooting an original roller is the best! Reloading the spent shells is a major PITA!!! So, what I'm wondering is, should I install a modern tang sight and a lyman 17 to get a better sight picture, or is a four inch group normal for these jury rigged rf loads?
