Steel for shotgun barrels

Many gunsmiths have parts that they will sell.
My local smith sells old barrels that are damaged but still good for that purpose for $20
At that price I would not even try to make a set of barrels.

Pressures in a smoothbore pistol like that would be low, but mild steel can have a lot of flaws in it. Like they said, better off using DOM tubing for that. It should do the job and is available. Do a search here in the archives for DOM tubing. There's been a bunch of posts on it. I seem to remember a particularly good one from Zonie.

The essence of my posts about DOM tubing boils down to this.
It comes in many different materials, and without a specification sheet it is difficult to know what it is made out of.
In my opinion, the low carbon steels are not the proper material for a barrel made out of tubing. Even the chrome/molybdenum (chromolly) steel is relatively weak unless it is properly heat treated.
DOM tubing is Welded tubing. It is not seamless tubing although it looks like it is.
DOM means "Drawn Over Mandrel" which is a process of smoothing out the weld bead and sizing it so it will work with the pressure fittings commonly used with tubing.
It is not as strong as seamless tubing, and I wouldn't trust it for a gun barrel even though some others do use it for that purpose.
The only thing I can say about their use of it is they undoubtedly know exactly what alloy their using and have the "Cert Sheet" to prove it.
They must also have had a extensive stress analysis done to prove it was safe to use in their guns.

If you get a chance to see Brockways book on building muzzeloading shotguns, you will see how he uses old damascus cartridge barrels for this purpose. I suppose if you could find an old 20 guage barrel you might be able to cut it back far enough to make a usable pistol. It would be somewhat wide, but still might work pretty good.
