I am impressed big time. Very nice job semi. Ok when do start the production run. I want one.

Does Green Mountain make a fast twist barrel that would fit this?

I wish they did Chaded. Their LRH barrels are only available as drop in models with the breech plug, sights, thimbles, and wedge tenons already installed - none of which are needed for this gun.

I did buy two of these though - one in .45 and one in .50 caliber. http://www.gmriflebarrel.com/blackpo...eloaderbarrels

Eventually the gun will have the original .54 ball barrel, plus those two shorties, and a .58 caliber GM round ball barrel. Maybe even a .50 or.40 round ball barrel.

At the last gun show I attended I picked this thing up. The action is rusted closed, but the bore looks pretty good and it has plenty of meat at the breech end for a breechplug. It will be added to the stable one day.

I can see it now with all these options...."Semisane's Swamp Dragon....the last gun you'll ever need!" Or maybe you could call it the "Swap Dragon" since you can swap barrels.

That is pretty amazing. I very nice looking rifle too, can't wait to see a range report...

I waited a longtime to see this post and it was worth the wait. I kept popping in just to see if you had finished, very nice.

Well I am so impressed with this rifle Semisane built. I hope he does not mind but I want to show the steps to a friend of mine. This buddy of mine is a machinest. And in his shop is every metal fabricating tool that I know of. And he can really use them. I am going to have him cut and crown a barrel for me Semiesane (thanks for the idea). And I will take my notebook over there and let him see this post. Maybe I might have to see what he has in stock for metal and time.

I'm really impressed with the rifle cant stop looking at the pics. In the 50ies and 60ies we made under hammer rifles from pipe and old barrels..(Allen style ) You have taken the under hammer to a new level,. Thanks for the pics.

That is just beyond impressive. That is some serious tool/folk art creating. That lock group is the most concise design I have ever seen on an M/L.

I love it! and wish I had the skills to do something like that especially since I would like to have an underhammer. Can't wait for the range report.
