[Thor]

Always (where possible) clean from the breech end. I have seen a 7 mm mag ruined by cleaning excessively from the muzzle with not muzzle alingment control piece and the rifling was worn enough to make the bullet yaw off targer. After having the muzzle cut and recrowned it shot great again, but I am sure velocities were down taking off 1-2" of barrel with a magnum round. If you have to clean from the muzzle use a tool or better yet a plastic or softer rod (wiped clean of course) Revolvers, muzzle loaders, etc and some autos fall into this category! Thor
