There have been debates about the protection ability of bore butter since I first started using it. After my rifle barrel got so gummed up it would not shoot straight, I cleaned that barrel free of bore butter and never went back.

If you want all the bore butter out of that bore... boil some water in a tea kettle.Pour a little dish soap down the bore, and then fill that barrel with boiling water. Do this about three times and you will see the stuff come floating up to the top and out the bore.

Then WEARING SOME QUALITY LEATHER GLOVES ... grab that barrel and swab that bore with a quality solvent on a patch. After a few of them solvent patches, things will really start to come clean.

I use Simple Green cleaning solution on patches all the time to clean out the fowling. It really pulls the fowling out of the rifle barrels. When you want to swab the bore on the range, simple windex will do the job. But to protect the bore of the barrel, I use a good quality gun oil, not bore butter.
