I built this 20 gauge flintlock using a Stevens single shot barrel. I cut the chamber off and had a breech plug made and installed. The machinist told me that he could have bored the chamber out and soldered in a sleeve that would have given me another couple of inches barrel length. It was a handy canoe gun that I sold on the forum awhile back. I didn't like the way it handled due to the length and I don't have a canoe so I let it go.

That's a pretty serious conversion, more of a build from the ground up than a conversion. Those barrels are hefty, and I've always thought they would let themselves well to threading a breach. Those are the ones that I've seen converted to muzzleloaders by threading the breach, adding a plug, and drilling 209 primer holes, but definitely not a flintlock.

This is exactly what I want to do. Just need to find a long barreled 20 gauge shotgun.

I assumed that this project was based on the fact that you already had a barrel. It would probably be much cheaper and easier (unless you're a machinist) to just buy a muzzleloader barrel to start with.
 
209 primer conversion is not what I meant. Sorry, it is the exact opposite of what I am trying to do which is a round barreled flintlock build like The Crisco Kid, did.

The barrel I would like to buy is not available at this time or I cannot find one to purchase, I was offered to purchase one that was longer, had a dent in the barrel, no maker info for $270 shipped so i figured I could find an old single shot 20ga and build from it. I have tapped and threaded breech plugs before so that is a non issue.

Okay, I think I misunderstood what you were trying to do.
 
That seems more in line with what a barrel should cost. $270 is nuts.
Although the old single shots are not as plentiful as they once were for cheap.

What I was originally looking for was an octagon to round 36 inch barrel. New at TOTW $249 plus Breech plug $12 plus shipping. Not in stock. It seems that these types of barrels are not in stock everywhere I have looked online.
 
Sometimes not in stock is code for something not made anymore.
Just look at all the not in stock descriptions associated with GPR's.
 
I’ve seen an adapter for them to that just pops in the back and then is loaded like a regular muzzleloader. And I myself have thought about dabbling in it.

20 gauge to 209 Muzzle Loading Adapter

Not sure if that what you are looking for or just a full on modified barrel.

I looked at the adapter and read the info it says black or sub only no smokeless .If it is a barrel for smokeless it seems you could use smokeless powder in it .Just seems odd to me
 
my next two projects are going to be a 410 and a 16gauge.both barrels are hardware store guns made in Chicopee Falls. just waiting to get a couple other projects done first. then a full clean up of my shop. somewhere in the clutter are the tools i will need.
What a full cleanup lol It will not last but a day or two if you are like me but go for it

I was thinking the same. I figured that was what I would use for the time being until I bought a real deal muzzleloader made specifically for my needs.
