Alright, I cleaned the Flinter with boiling hot water with a bit of Dawn in it! First I scubbed the bore with Butches Bore shine and poured at least 2 quarts of boiling water thru! I couldn't believe the junk that came pouring out of it! I poured the hot water thru until nothing but clean water came thru! I then poured Boiling clean hot water thru until it was gone to heat up the barrel so the water would evaporate!
I then ran about 10 dry patches thru the bore until they came out dry and clean! After that I used Bore Butter to lube the inside of the Barrel! The first patch or 2 came out with very little brown on it. I ran another and it came out clean, nothing but yellow from the Butter.

Is this good enough to prevent rust in the bore??? Should I just run a Lubed patch thru and let it sit?? Or should I run a patch thru with gun oil instead of the Butter??

Sorry for all the question but I want to get it right, Thanks for all the Help!
