maybe im measuring the barrel wrong. I took it off an measured the whole barrel except the hook where it connects to the stock. I don't know the term but i think im including the breech? where the powder sits and there is no rifling. if i didn't include that it would be 28"

Yeah, you measured the breech too. Ok, that makes sense now.

I'm guessing a trade rifle that someone put a big patch box on it. Unless one was offered at some time. A call to Lyman might get you the answer.

Your gun definitely is a lyman plains rifle.I have one in 54 made in 1977.It has 1 wedge and a different patch box than the GREAT plains rifle.The barrel will interchange with the trade rifle,or so I've been told by others who I do trust.A super rifle just a little older than the great plains.

What do you think makes it a plains rifle compared to the trade rifle?

Ah ok. That looks like what it is. I never saw one before.

You can determine the twist using a tight fitting patch on a jag. Be sure to use a rod handle that allows the rod to rotate. Insert the rod/tightly patched jag fully, then put a mark on the rod right where it exits the barrel (a vertical line would be best). Slowly remove the rod from the bore and watch the rod rotate. Estimate the amount of rotation of the rod (example - 1/2 of a full revolution). Measure the length of rod you had inserted between your reference mark and the end of the jag.

If you withdrew the rod 32" and the rod turned 1/2 revolution - your twist is 1:64 or very close.

Length of rod divided by fractional number of revolutions turned.

Edit: I suppose you would need to subtract the section that isn't rifled from the length of rod.

Looking at the barrel.. I would guess it is a Trade Rifle barrel. That means it has a 1-48 twist. My .54 Flintlock shoots a .535 roundball with 90 grains of 2f black powder very very well. It also shoots Powerbelts 405 grain .54 caliber. And my .50 caliber Trade Rifle shoots sabots real good.

So you can call it a Trade Rifle, but with all that brass I might be called a Hawken rifle also. Or you could call it ... "Bob." It is still a fine rifle.

You need to read the other posts. It's been identified.

Muley I did not see his link. But did see a question he asked me and thought it might be rude not to answer. So I am glad it was discovered what model it is. I had never seen a "Plains Rifle" but I would still guess it shoots well with a .535 roundball and around 90 grains of powder. At least that is where I would be looking.. if the Plains Rifle was mine.
