Barnes' specially formulated CR-10 bore cleaning solvent effectively removes the toughest copper, brass and lead deposits. Leaves rifling clean for top accuracy and longer barrel life. Dissolves layers of corrosive carbon and powder build-up in the throat area caused by repeated exposed to extreme temperatures. This is particularly critical to extending barrel life of high velocity rifle cartridges. When cleaning a rifle, angle the muzzle downward and use a bore guide. This ensures solvents, crud, and grime won't drip or run through the action, gumming up the trigger and possibly damaging the bedding. 1-piece, coated cleaning rods are recommended.


  • Use the proper jag and a tight-fitting patch soaked with Barnes cr-10 bore cleaner to remove the powder fouling
  • Install the proper size cleaning brush, soak with cr-10 and stroke the bore 10-20 times
  • Examine muzzle and throat area for any signs of copper fouling
  • Push 2-4 patches soaked with brake cleaner through the barrel with one long stroke for each patch
  • Clean inside chamber with a dry patch
  • Lube the bolt lugs with bolt grease and clean out the lug recesses, also apply a small amount of grease to the bolt handle and cocking piece camming surfaces on the bolt
  • Coat the bore with a light coat of oil then run one dry patch through the bore
