I have been taught that cleaning a precision firing weapon consistantly = accuracy. I have been in a few recent debates that invole cleaning. I also realize that this is a very opinionated topic. I clean 3 Copper Solvent, 3 Powder Solvent, Then 3 Dry. Now this is on a 7.62x54 weapon. We count rounds and shoot alot to collect data for that first round hit capability. My real question is do you have to clean it untill all of the copper streaks are out of the barrel, and you cannot see them anymore in between the Lans and Grooves? (with good lighting looking down the crown end of the bore) I am interested to see the response and looking to learn something new.
