High pressure pipe used in hydraulic rams are probably strong enough , you can shrink reinforcing pipe over the breach area if needed . If you can get some , railway waggon axles are supurb steel , bore them out for a morter
That would be nice and smooth and round and constant diameter being ground.
Shed 80 pipe could be another option.

Yep shed pipe is seamless, I use shed 40 for mine but I only get to a max of about 1500 psi
oooh I might have a length of stainless pipe came off a sonar, wonder if that would be strong enough.
@spanners think I read somewhere anything over 20mm is a canon...cant remember where off hand.
So my tiger tank's 88mm is fine then....
:D

Yes I know, some people reading this may not and may end up using any old pipe.
Plug Welding the chamber when using Seamless pipe is critical and will create a weak pont in your cannon ...
One thing you dont want is your cannon going at both ends at once.

There you are Gimp , It used to be an antique if it was an old gun that ammo wasnt currently being manufactured for . Lots of us had 455 pistols , then Fiocchi started making ammo for obsolete firearms and the 455s etc went on ticket . Then an idiot got a pistol for home defence , it was an old French prototype revolver , and even though there was no ammo available it shot with 450 corto ammo , which expanded into the cylinder but still worked , there was a court case when he treatened his girlfriends husband with this gun , and as the jury couldnt understand how a gun could fire ammo that wasnt made for it he got off , so when the law changed they lumped everything that takes a cartridge except pinfires , onto an appropriate licence . If you have a muzzle loading antique rifle or shotgun you dont need any licence unless you are going to shoot then an A applies .
