"Shouldn't" is not the same as "won't".Buy an oak dowel from your hardware store, they usually come in 3’ lengths. I use these when slugging barrels. Will not damage your barrel and shouldn’t splinter.
Did it work?Shadow said:Bought a cheap brass rod. Gonna tap the old rod the rest of the way
Tried that, would not budge eitherif any bit of the cleaning is out of the muzzle, clamp it in a vise and pull on the stock. You might need a friend to help.
That will attack the metal, as well.How about using BLEACH to rot the cleaning patch.
But lye wouldn't. We cast iron cookware collectors use lye baths to soak cast iron in to remove old gunk and seasoning. It won't hurt steel/iron (don't use it on aluminum though) but it will dissolve anything organic - including cotton cleaning patches. It takes a while though. It would certainly be worth the try. Remove the barrel. Temporarily plug the breech end and fill the muzzle end with solution (mixed at the rate of 1lb of lye to 5 gallons of water). Then, put a really good plug in the muzzle end (plastic plug that won't get eaten by the lye), turn it over and fill the breech end. Plug that and let it sit vertically (hanging over a plastic bucket in case the plug leaks).That will attack the metal, as well.
But lye wouldn't. ... it will dissolve anything organic
That is what cast iron cookware restorers use. You mix 1lb of lye drain cleaner to 5 gallons of water and soak your iron for a couple of weeks. It dissolves all of the grease, gunk, and old carbon seasoning. Same kind of solution in this case (but with a small amount just to fill the bore) would dissolve that patch in a few weeks.Which is why most drain cleaners are lye. Breaks up organic matter in short order.
