Well, I just went and blued it. I didn’t feel like stripping the under rib that I had that was blued, so after I fitted and drilled the insert that replaces the drum, and holds the touchhole liner, and got it tapped for the touchhole liner, polished all the flats, and hung it in the 90° Missouri sun. Once it was so hot I couldn’t touch it with my bare hands, I started applying the cold blue. It got 3 coats that way and I am happy with it. I’ve just got to wait for my rod pipes and cleaning jags to come in and I will finish it.
In talking with the fella who I got this barrel from, he showed me the 12 ga barrel, and I can’t use it. It has a button breech, and I don’t have the time to mess with converting it. I may take the 50 cal barrel that I bought for parts since it has no breech plug, and find a shop that will bore it out to a 20 ga, thread it for screw in chokes, and make a new breech plug for it.
