Ideal steel for muzzleloading pistol barrels

The short answer is no. I have seen barrels made from tubing but it was
high pressure chrome moly seamless tubing. An engineer made them at home
using his own rifling machine. But he worked at a power plant and knew what
he was doing as far as the tubing he was using. You have to know what is the
pressure limits of the steel, both tensil strength and radial strength and notch
strength. I am not an engineer but the short answer is no.
 
I would imagine so, some small pistols are made of brass. Old, cheap, guns had barrels of cast steel. If I were looking to build a cheap mz pistol from found materials, I would look for a used car axle, they are generally made of 4140, or similar, which is good for smokeless. Most scrap yards will sell you that kind of stuff for weight price. It will have to be annealed to work with a standard high speed drill bit. I met a barrel maker from Canada who made a benchrest schutzen barrel from a piece of re-bar, it shoots superbly. Re-bar is generally made from a mix of metals including old rail road scrap, it is a medium carbon steel.
 
I know Davide Pedersoli makes a Queen Anne's pistol with a brass barrel.

Not sure of the composition though, or if it's specially made or not.
 
Yes. Of course you can. Should you? It's a matter of what you plan on doing with it. And, if you were to let it go to someone else what would they be doing with it? Want to go hunt elk with it, or shoot some paper at 25 yds? Big difference. I've made 1" bore cannons out of similar materials. They shoot 1oz BP with a 1" steel ball. A pistol takes such a small amount of material that I would just use something where the question would no longer need to be asked.
 
Ideal steel for m/l pistol barrel

I am planning to make a m/l pistol with a 6mm bore made of mild steel for which I have recd. different opinions. some have approved it while others have rejected it. What would be the right steel & what kind of treatment should it undergo.
 
The way i understood it is that mild steel is the closest thing to the period correct wrought iron available to most of us.maybee not the best material available today but for sure useable if other safety considerations are adhered to such as wall thickness and BP only.

unless your an engineer i dont know that i would try heat treating the mild steel to make it better as you may just end up making it worse and very dangerous
