Hi Chris,When I'm shooting at the range i use Thompson's #19 bore cleaner between shots so I'm always shooting through a clean barrel.When I get home I use hot soapy water to clean the bore and breach plug.A pipe cleaner works great to get the breach plug hole really clean.After I swab the barrel one more time with #19 Cleaner I run dry patches down the barrel. After that I run a patch with bore butter down the barrel, grease the breach plug threads and reassemble.Ialways run one dry patch down the barrel to remove excess bore butter from the barrel before shooting again.Hope this helps.Mark
