I got a 1939 8mm Turk Mauser with Gew98 action. Finally decided to take it to the range yesterday and ran 15 rounds through it. Cleaned the bore with Windex because it was old corrosive mil ammo. Followed that with Hoppe's #9 and give it a rest over night.
Today I run a clean patch and it comes out brown and green. Scrubbed it again with Birchwood Case bore scrubber this morning. And again this afternoon. This thing isn't getting any cleaner. It's getting dirtier! It is the dirtiest barrel I've ever seen.
Got and good home brew cleaning methods that won't wear out my arm and cleaning rods?
