What Breech Plug

[hanshi]

I have most of an old CVA Mountain rifle - the one with two wedge escutcheons.  I have the stock, misc hardware parts, and the Douglas barrel (.45, 15/16" I believe).  It is threaded for a plug into which the drum screws; a "patent" breech??  There's no lock so I want to rebuild it and convert to flint.

I've searched through the TOW catalog but just don't know what I'm seeing.  Can anyone point me toward the proper breech plug, keeping in mind it will be converted to flint?

Hanshi,
You should be able to just replace the drum with a vent liner. You might need to re-tap it, but that is where it goes.
Is that you over at Cast Boolits?

These are examples of breech plugs. You have the one that threads into the barrel, without a chamber.
I like mine. I am replacing all the furniture.

Here is the replacement lock.

This one is percussion. There is a counter part in flint.

With minor work, these will drop in.
The trick, is to get the drum out.
Heat the barrel, soak it in penetrating oil to cool it. It should come out, but they are in TIGHT! Not like ordinary drums.
Next, get a replacement vent liner. You may have to retap the barrel/breechplug. Not a big deal. Also, it will help to mildly counter sink the threaded area. This will allow the liner to be replaced with a drum again if needed.
When you install the liner, make sure the screw slot is in line with the bore. This prevents powder, or at least makes it harder for powder to drop into the stock.
It is fairly straight forward to do this.
Approach it like it is a new barrel, only it has a starter hole.
That will be a sweet rifle when it is done.

Yeah, it's me.  There are several forums I post on from time to time.

Thanks for the tips, guys.  I don't have the original drum so flint it is.
