If there are any chunk builders out there that want a project to keep them busy this winter I have the start of one for you.
I have a Getz .50 x 45" 1 1/8" #20215 chunk gun barrel I lost the breech plug.
This has been in my barn for almost 10 years. I put it there along with a few other bbls after my house and shop burned. I had a 1/2 gallon of reagent grade Nitric acid in the shop that vaporized (read as coated everything with a fine mist). The outside surface of the barrel has a "patina" (read as looks like $#@*) the bore had been well lubed at the time so it held up well. I am building a rifle with one of the bbls right now, I had Don check it out and it came thru the ordeal straight but well aged.
If it's something your interested in let me know-you pay the freight and the bbl is yours, it is too nice to toss out and I'd rather see it go to someone who will use it.
