Newb question(see the name)I just cleaned my 14" fabarm for the first time and have noticed that the 25% of the barrel closest to the muzzle is dull. This dull area isnt even so it cant be there on purpose its just....smudgy while the rest of the barrel is shiny. Multiple passes through with the brush and patches/hoppers havent made it shine again? Its eaten a ton of shells before cleaning as well as a box of slugs. (or two)
What causes this? Do I need to hook the brush up to my drill and just go for it?
