Re: Muzzleloader question
+up to above comments.
get a bronze brush, you'll have no problems. stick a rod guide on your cleaning rod. (has your 'advisor' not heard of this innovation?)
hot water and dish soap works well in the cleaning process. LIGHTLY oil, afterwards. been shooting a Fayetteville and a Smith Carbine for ages, with no ill effects using bronze brush and soap and water for cleaning.
I don't know if dogs have a heaven, but there will be dogs in mine.
