I have a .58 calibre range rod,bore moppes and brushes, even a breech scraper.I remove the barrel and nipple.Fill a bucket w/ water and put the barrel in, then pour water down bore.I let it sit and soak while I clean the nipple w/ a pipe cleaner and lock.Next, I return to the barrel w/ my range rod, run the brush, then the jag w/ cotton flannel cleaning patches.Run several pipe cleaners through flash channel. Remove barrel from bucket and rinse.Put the kettle on the boil, then pour the hot water down the barrel.Run dry patches till bore is dry then lubricate w/ sweet oil,quickly, so as to prevent flash rust.Oil nipple threads and reinstall,wipe down and oil exterior of barrel.Reinstall barrel.Oil stock.Done.Best regards,J.A.
