One fella on here told me how he does it and ive seen his groups and they are inpressive. Doesnt mean it works but its not hard how he does it so i dont think it hurts. He takes j-b bore paste and does 200 strokes to the barrel with a cleaning jag (new patch every 50). Then cleans the barrel out and takes it to the range and sights it in. Just make sure u dont over heat your barrel when shooting it. Good luck.
