1874/80 Gras 11mm shotgun

[tactical870]

I picked up an 1874/80 Gras rifle in 11mm which has converted to a smoothbore shotgun. Anyone know of a source for brass or a case which can be fireformed to make a straight wall case? Anyone seen another of these?

I think they are out there. Sounds like a very cool 410 ish cal antique shotgun. 11mm gras brass is maybe what you want?

I was hoping I could find something a little more common to use as brass. Otherwise I'm leaning towards sleeving the gun down for 357 mag....

11mm Gras can be made from 348 Winchester.
