Made in '75, so its a black powder cartridge double
one of the guys that shoots our Safari Rifle shoot (
http://arizona-rifleshooting.com/safari-rifle-shoot-PRGC.html ) collects and shoots BP doubles.
he spends months developing a load, bullet weight and style and powder charge, that will put both shots close to the same hole, doubles are "regulated" when they are built so the at some distance both barrels shoot to the same spot, even as the gun recoils to the right with the right barrel and to the left with the left barrel and up with recoil, etc.
have fun with it!
Buffalo Arms might have a bullet that fits and maybe brass, Bertram might have brass for that caliber or which can be cut or sized to that chambering.
shoot good!
