Cheap or used, I'll probably never use it again. I have a poorly made blunderbuss barrel. .72 caliber,from breech to muzzle. The barrel is flared,but the bore is not.
1" to 1-1/8 would make this work.
From a non completed kit I bought....semi trainwreck

alex e.,
Don't know exactly what you want by the description, but a #4 morse taper reamer is about that size. Try McMasterCarr, but only to verify size and correct nomenclature in this case. Then use that info to do a web search for a cheap reamer. With a more detailed description of your needs, a cheaper or homespun solution may be available.

Muzzle flair? Use a lathe?

PM Me. I may be able to help.

That is a lathe job with a boring bar.

Scota4570 is right and buying a #4 MT reamer for a one of a kind job would be an
extravagance of the worst kind.

Alex E, you may want to have a pilot on the reamer that is bore size, to keep it straight.

Make a cone-shaped piece of wood with a dowel on the center axel. Glue emery paper to it in stages from coarse to fine and just sand the bore out to the diameter you want. All the accuracy you are after is hitting a man-sized target at 7 yards.

Alex, I sent a pm on a place that may have that in surplus.

I would be very fearful when it comes to shooting a big bore barrel like that wasn’t made by someone that knew what they were doing. It obviously was started by someone with only a tiny bit of knowledge of such weapons. Do you know what kind of steel was used? After all a blunderbuss is just a small canon that stocked up to be shoulder fired.

To turn a reamer into a .72" bore would take a HUGE amount of H.P. Even if you could secure the barrel rigid enough, you still have to keep the cutter sort of centered while you rotate it. Make friends with a small privately owned machine shop, the rewards will go far beyond this one gun barrel.

I found a machine shop near where I was working that was able to do it. It's not perfect as far as the taper matching the barrel profile. But its alot better

This barrel was part of a parts set from Pecatonia. If it hadn't been cheap. I'd have never bought it

That is a fairly simple boring job.
