Hello,
After cleaning my gun after shooting yesterday, i could still see copper "streak marks" that follow the twist of the rifling. I assume that these are caused by the FMJ bullets i was shooting.
I currently use MP-7 to clean my gun. But it still didn't remove this. Should this be a concern? should you be able to clean a gun barrel till it's chome shiny?
What do you guys used to clean it and the procedure? thanks!
