5. DO NOT pull used patches back through the bore Refer to the Bore Solvent Manufacturer s instructions for relevant Health and Safety precautions Solvents must be used sparingly any excess spillage outside of the barrel must be removed immediately Only use the correct size Jag and Phosphor Bronze Brush for the barrel for example J30 amp PB30 for 308 Never use a bore brush in a dry barrel Always wet the bore with a patch moistened with bore solvent before using a brush Note The bore and chamber are easier to clean after firing whilst the barrel is still warm Where possible it is recommended that a cleaning rod and a rod guide should always be used when cleaning the barrel Using a rod guide ensures that the cleaning rod is held in the centre of the bore which reduces the possibility of damage being caused to the chamber and bore during cleaning However care must still be exercised when using the cleaning rod The use of a Pull Through or Bore Snake is not recommended for routine cleaning If a pull through is to be used it must be pulled from the chamber to the muzzle and care must be taken to ensure that the cord is pulled centrally out of the front of the barrel to avoid damaging the crown The pull through or bore snake MUST be cleaned regularly to remove grit and debris that could damage the bore of the barrel If a Pull Through or Bore Snake has been used the Barrel should be cleaned using the method defined in
