So do you usually end up using a bore brush that's one size smaller than the actual bore to allow for the Frontier pad?

Not if I can find a real 10 bore brush

Most are 12/10. So I use a new one to get as tight a cut as I can

Refreshing/Refinishing Damascus Steel
 

I never had advised refreshing or retouching Damascus steel, Just wipe out cleaning and lubrication is all, reason: pattern is a result of rub off oxidation that is held different by hard layers steel then soft ones. Restoring finish done by confident smith is the way to go, again if done properly as restoration it will not devalue the firearm. My simple philosophy is: "people made it, people can make it again"

I agree with Jeff--BALLISTOL!! about 20 years ago a local gunsmith introduced me to Ballistol and I have never used anything else. No G-96, WD40 or Hoppes(although I still love its smell and its memories). Its also great for black powder cleanup. If you can look up its uses and you will be impressed and convinced. BUT please and I repeat "please" do not follow the recommendation to use it on open wounds(unless your severely wounded in a southeast jungle or some desert under enemy fire) because it makes Iodine feel like water. For all and anything else its unbeatable. George

000 steel wool and Kroil works great.
