Hey all hope yall are in good health, I recently acquired a Thompson Center Arms Omega that had been shot and never cleaned. Don't know any of its history. I have used soapy water with baking soda (I oiled the bore with lucas heavy duty gun oil after wards )and lucas bore solvent mixed with T/C Muzzleloader bore cleaner and baking soda to make a abrasive compond with a Brass Bore brush and theirs still a thin layer of rust that's redish brown
(I think) in the Bore Im also going to paint the barrel with Brownells aluma hyde II. I'm stumped and any advice would help
