Make sure the jags and brushes are not brass if you are using a copper solvent (which you should be using). The solvent will react to the brass and you will get blue residue on the patches forever because the solvent is reacting to the jags and brushes even if the bore is clean. Bore Tech products prevent this. Also, look at a purchasing a quality bore guide (fits into the chamber). Push the jag/brush only from chamber through the bore, and don't pull it back through once you push it through the barrel. I have tried many bore solvents and the one that works best for me is BoreTech Eliminator. Most solvents that contain ammonia will damage the barrel if you leave it in too long. Bore Tech will not and it says on the bottle you can leave it in that barrel after cleaning to help prevent rust.
