Hawken Kit what do i have ...

Looks to me like that breech is solid and the recess is simply that…not a plug.   Hard to tell from pics.    If that is the case it’s probably ok to fire with reasonable loads.
A good cleaning, and a “tied  down” test fire might be in order.

This picture shows it quite emphatically.
No trouble shooting that rifle. I might pull the drum to see how many threads are engaging, though.
It is likely just fine to shoot. I would have no trouble or worry about it. I didn't see this picture of the patent breech before my other post.
Definitely a decent breech, just not as common, being a drum.
I would scrub the bore with a bit of 0000 steel wool on a brush, nylon or bronze bristle, with some light oil on the steel wool, then use a dry cloth patch to clean out whatever is left in the bore.

Rifling looks pretty good to me.
Will it be difficult to clean that last bit, with the drum coming that far into the hollow in the breech plug?

I’d file the intruding part of that drum off.

Whetrock, Rich,
That isn't a picture of Klauss's rifle - it's a picture Eric Ewing posted as an example of Large's rifling.

Klauss,
Not knowing German or EU laws in general, what is the possibility that this is a muzzleloader that has been "deactivated" to make it a non-firearm. U.S. federal law does not consider a percussion muzzleloader to be a firearm (some states have stricter laws), but my understanding is that Canada DOES consider a percussion muzzleloader to be a firearm with all the ensuing restrictions. Our Canadian brethren can better explain/refine if they want. Does German or EU law place similar restrictions that might have resulted in this being converted into an inoperable display piece? There are just enough oddities with it that make me go, "Hmmm...."

[whetrock]

Yes, thanks. I guess my question about the drum is the same. But, yes, thanks for pointing out that this photo isn't from Klauss' rifle. Sorry for the confusion.

I do not know the EU laws concerning muzzleloaders. Here in Cda. all percussion guns are no different license wise, to a modern rifle - all firearms & to be in possession, must have a firearms license.
Flintlocks, wheel locks and matchlocks are not deemed to be firearms for the purposes of licensing, but are firearms for all other purposes. These may be possessed by those who people who are banned from owning firearms due to, for example, an assault charge. Same deal with bows and arrows, flinters and bows OK, percussion guns no.
