I normally clean my rifle (marlin xl7, 30/06) after every range session. Thought I would try the "shoot till groups start to open" method and kept the barrel dirty between sessions. On the second and third session(different day), the first shot would be 3 inches high from aim point, but all follow on shots are near point of aim. About 40 rounds per session. Thoughts?
