Im sorry maybe you did not understand the 4 or five post that suggested a bore snake or the couple that suggested the otis cleaning kits . . Both of those cleaning systems will rid your barrel of all bullet residues left behind . With little to no chance of harming your bore . Or were you asking something else we all did not see ?
Curious. Where did the OP indicate a lack of understanding, given that he had only two posts...one asking the question, the other saying thanks?
