Hey all hope you're in good health, I recently acquired a T/C OMEGA, I don't know any thing about its past besides it had been shot and never cleaned. As far as cleaning goes I've let the Bore sit with solvent in it, used soapy water with Baking soda, I even made a concaution with bore solvent mixed with baking soda. And the thin layer of rust won't come out which the barrel has shallow pitting near the breach and muzzle with none in-between here are some crappy photos
and the rust is a redish brown. Any advice will be help full thank you all
