well I ran super hot water through it until it came out clear, ran some rags down the barrel, used a q-tip to clean out the drum, soaked the nipple in hot soapy water and ran water through it again just to be sure. let it sit for a while and gave it a light coat of bore butter. some may say it's a gimmick product but for $7 a tube I think it's a negligible expense. it definitely helped slow down rust deposits on my dads muzzle stuffers up on the mantle and it definitely helps with loading. my brother in law swears by it though he has a home made bullet lube that he likes more but he's too stingy with it so I have to just use bore butter as a bullet lube as well.
