it will shoot steel BB's lead BB's and pellets quite happily. The pellets are the most accurate.It is quite easy to load the shells without removing then from the pistol. Its not as accurate as I would like but the sights are not exactly target sights. I think the cylinder is a bit small for a .45 peacemaker; there is a bit of a gap between the cylinder and frame and the walls of the cylinder are not thick enough for what are basically .357 cases.
