If you use your gun frequently, the easiest way to reduce the adverse effects to a minimum is by using Diamond Line. In our tests with the Diamond Line Bana, the bore did not show any significant traces of tombac deposits and still ensured high accuracy after 10,000 shots using calibre 6.5x55.
The best way to dissolve burnt on powder residue is with a good bronze brush of a suitable diameter and an effective cleaning oil. Before putting your gun away every time you shoot, you should use a brass brush and oil for cleaning to dissolve any powder slime. Then rub the bore dry with a soft cloth.
If the barrel has old, hard powder residue on it, wind a cloth round a worn brush and apply J-B bore cleaning compound, Gold Medallion or Remington Bore Cleaner to the cloth (see back).
Where powder residue is old and hard, repeat the procedure every 300 to 500 shots. The two soft pastes are not too abrasive and slowly liquefy as you use them, which means they do not damage the barrel.
Use a rod guide to ensure that the cleaning rod is centred and as little fluid as possible gets wasted. After cleaning, oil the bore with a gun oil to prevent deposits from forming as quickly.
Recommended bore cleaner Tombac solvent:

.22 LR and lead shot
If you shoot with .22 LR lead or shot, clean the barrel with a brass or steel brush soaked in a nitro solvent gun cleaner to dissolve the lead. Then wipe the bore dry and oil it with a gun oil.
Divide the barrel into three sections. You can place the barrel muzzle against a wall to prevent the brush from going beyond the muzzle. Then clean the barrel with a cleaning oil and soft cloths.
