A few problem holes

[guncrank]

A couple of screw holes completely into a shotgun chamber.
This is a card shoot gun with a 48 inch custom barrel.
The owner won in a side bet.

The gun had the brass piece as some form of riser or a cover up

Customer wants to have a scope mounted to use.

Any ideas?
I was thinking of soldering the brass piece back on with soft solder and fitting long screws to fill the holes and machine flush with chamber.

FWIW, I wouldn't think of shooting it, w/o the screw holes TIG welded shut & the chamber refinished - to say nothing of the liability involved if that wasn't done, and a 3rd party (like a customer) got injured some day (not necessarily the first few times it was fired).

I can't tell from the picture what is involved or even if it is a shotgun. But I will say that even though shotguns are relatively low pressure, holes drilled into the chamber are not good. I don't think I would want to fire such a gun even if the holes were welded closed.

I am curious as to what the previous owner was doing with the gun. Was he firing it?

It is a card shooting shotgun, a outlaw gun

Customer wants to have a scope mounted to use.

I would start by figuring out how to put a scope on it.
Then, plug the un-used holes with plug screws, tig weld the tops and blend the bottoms inside the chamber.
Then mount the scope base.
Make sure all the screws fully protrude inside the chamber so you end up with them filling all of the holes inside the chamber.

It is only a shotgun barrel, which really is "Soft steel". If the holes are only 8-32 or less I would not be afraid to put the screws in. I don't know how equipped with machines you are, but I would then make a steel scope base and silver solder it on. I bore a slug to the tube diameter leaving plenty on the OD of the slug to work with. Machine the OD to take a Weaver base (The easiest to work with), split the slug and mount a scope on it to check position before soldering. You may have to take in to consideration the taper of the barrel and build it into the base.It is deceiving where the scope should sit on a single shot, so check the position before soldering. There is hardly any pressure at the chamber area. Just look at the construction of a shotgun shell. I have seen many shotgun tubes split like a banana peel pulled apart in the middle, but never seen a chamber area split.
