Need to get rust out of my bore

Fishboyat said:

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 brownView attachment 351183 View attachment 351184(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

IOOSO gun cleaning paste, available Midway USA, a light abrasive paste made for scrubbing barrels. Less aggressive than valve grinding paste. $4.79 tube.

Cut a square of scotchbrite pad and put it over an under size jag. Use a light oil, WD-40 is fine. Scrub til you're happy.

Don't worry too much, you'd be surprised how well a rough bore can shoot. Probably not national match accurate, but definitely minute of deer.

Really and truly we are talking about cleaning up a bore and not any unmentionable........

From your first picture I will say it looks like you have most/all of the loose rust out and any further cleaning will yield minimal results. The pits will be there forever without a freshening/rebore.

Go shoot it, several times 15-20 or more at a target and see what it does, then clean it and you will know whether to keep it or buy a better gun.

My barrel had a really rough spot about halfway down. I had to use a mallet to pound a patched ball through that sesectioni thought it would shoot out, but it didn't. I even used cream of wheat as a filler several times, but it didn't work.

This may be a bit extreme for you, but it worked for me. I used distilled vinegar in mine. You don't want to get it on the bluing. I stuck a toothpick in the flash hole. I stood the barrel straight up in a bucket of water. I filled the barrel with distilled vinegar, using a syringe. I let it sit over night. The next day I washed it out, good with boiling water and Dawn. I used a jag and patch to pull the soapy water through the drum into the barrel. After that I hit it with WD40, swabbed it out with a dry patch, and let it finish drying. Now I can load it with just hand pressure, and it shoots better than my eyes can see.

That's not rust, it's damage from fake powders. The only way to get rid of it is to get it freshed out.

This is what was in the back of my head while cleaning my rifle because the "stain" on the Bore didn't behave as rust would, so thanks for the info

I would shoot it and see how it does. I've seen some sewer pipes shoot great.
