I have a dumb question.. When cleaning with a rod and brush I know you should push it through from the breech end of the barrel but should you pull it back through or screw the brush tip off while its sticking out of the other end of the barrel then only pull the rod back through. I know you go back and forth with the patches but just not sure if it could damage rifling by pushing the bronze brush though then pulling it back to you? Sorry for the dumb ?
