HI guys
I have the urge to build a matchlock.
Does anyone know where to get a reasonable smoothbore barrel on this side of the Pacific that would suit?
Thinking of waiting for a 16 or 20 gauge shotty barrel but they will be a bit short and may look odd on a matchlock.

Just build what you want and enjoy it and them that don't like it can waltz Matilda in their own fashion. In fact I'd call it my 'Billabong' gun. I believe a 20 guage modern shotgun barrel would serve well and can be tapped for a plug with a standard SAE or metric tap; I did it years ago and it worked fine. Don't cut the chamber off if it has one, it will make a fine shotgun barrel. If you want to shoot round pumpkin balls you will need to cut off the chamber just behind the forcing cone. That way you have a straight bore. Also some early matchlocks had shorter barrels and some really weird stock shapes; you can get away with a lot and have a most useful piece. You can decorate it native style with lots of bone inlays, Dingo teeth, and kookaburra feathers and whatever pops up in your treks in the outback. There is no better gun for the trail than a smoothbore and it will be legal as poppies in China. (They are still legal, right?) Good luck and send us pictures of your creation and the trail! Thanks, George 1.

To create the breech plug for a 20 guage muzzleloader from a modern 20 guage shotgun, cut the breech end of the barrel where the shotshell goes off leaving about 3/4 inch (.750") of chamber before the start of the forcing cone.
The chamber diameter in the barrel has a diameter of .685". This is exactly the size of the minor diameter of an internal 3/4-16 UNF thread, (.682"-.696"). By threading the remaining chamber areas bore with a 3/4-16UNF tap you can screw a 3/4-16 UNF bolt into it for the breech plug.

This isn't ideal for a breech area because the best design has a square shoulder at the end of the bore for the breech plug to tighten against and all the altered shotgun will have is a forcing cone in that area.
This will cause a small amount of powder gas to blow back thru the threads when the gun is fired but it can be minimized by wrapping the breech plug threads with a few turns of teflon plumbing tape. The tape will seal off the leak.

Have fun. :thumb:

Many, many thanks!
I was wondering the best way of dealing with this issue.

I am also going to build a matchlock. You can get hollow bar from a steel mob in Melbourne that should do the trick. That is what I will use myself.

Cheers PM me if you like

HI mate
ended up getting a 20 gauge barrel. Have just abut finished the lock and am waiting on the wood from Vardy and a few bits from TOTW.
If you are interested, Rebel gun works has an old octagon to round single barrel shotty in16g and Cleaver has new Rossi 20 Gauge barrels.
Just finished cutting off the chamber and tapering the tiller.
Fashioned the mainspring out of a piece of ruler (now I can measure the trigger pull :) ).
Done more since this picture but:P1070366.JPG
