7. Thoroughly scrub bolt component parts in pan, flush with very hot water,or ammonia-based window cleaner, rinse and then wipe dry. Scrub thefront of the bolt face with a toothbrush to remove all traces of powder andcap fouling.8. Soak the breech plug in very hot, soapy water or an ammonia-basedwindow cleaner. Scrub its threads with a toothbrush. Thoroughly dry thebreech plug, making sure the flash hole through the nipple is clean anddry.9. Inspect all parts (including bolt, barrel, receiver, trigger, etc.) to be surethat these are clean and dry. Pay particular attention to the breech plugthreads inside the barrel.10. Oil the bore and all parts thoroughly with a good quality gun oil, then reassemble.However, avoid lubricating the striker, striker spring, or theinside of the bolt, to avoid oil spattering when firing or sluggish ignition incold weather. Remember to lubricate the breech plug/nipple assemblythreads with a good quality black powder gun grease prior to reassembly(See page 30).11. The outside (exposed) metal parts should be wiped down and lightly oiledto remove fouling and prevent rusting.NOTE: Several firms offer Black Powder solvents and these may be used in place ofthe soap and hot water solution. However, not all smokeless powder solvents willrender the fouling left by Black Powder non-corrosive. Be sure you use a solventspecifically intended for black powder fouling, hot, soapy water, or an ammoniabasedwindow cleaner, followed by a good gun oil.Sometimes, lead build-up can occur in the barrel throat at the muzzle of the barrel,and in the bore. If ‘leading’ is noted in your rifle, clean it out before it builds up andinterferes with reliable functioning and accuracy. A special ‘lead removing’ cleaningtool (for bore and chamber) is available from gun stores.! WARNING –LUBRICATIONOILFiring a rifle with oil, grease, a bullet, or anyother material even partially obstructing the boremay result in damage to the rifle and seriousinjury to the shooter and those nearby.

If the powder charge is affected by thelubricant, it may not be ignited, but the energyfrom the percussion cap may be sufficient to pushthe bullet into the bore where it may becomelodged. Firing the obstructed bore may damagethe rifle and cause serious injury or death to theshooter and those nearby. In the event of amisfire, always reseat the bullet fully onto thepowder charge before re-capping. Use lubricantsproperly.
