I had a quick question about using a steal bore brush to clean a Remington 597 .22lr. The barrel is not removable and there is no way to push the brush through from the chamber side. I have heard that you are not supposed to push the bore brush through from the muzzle end, IE against the rifling, but I wanted to know if this was true or not. If this is true, what is the best way to clean a .22 other than with cleaning patches. Thanks.
