Gras Modele 1874 M80
 

I have one of these French military rifles that has been in the family quite a while. Someone gave it to my grandfather a long time ago. It is an 11 mm and fires a black powder cartridge. The gun is in excellent shape. The bolt action is tight and the bore looks very good. I have toyed with the idea of finding brass for it and casting or finding bullets to shoot in it. Does anyone know anything about these guns, or where I can find brass?
