Hello,
I've just bought this unmarked combo hammer double in Germany and while waiting for it to be delivered in a couple of months, I would like to get some components for shooting the rifled barrel. I presume this is 24 bore rifle and I plan to experiment with shortened 24g shells (brass or plastic). As for the bullet, I would start with .58 cal. ball which is 14.75mm. Would much appreciate any suggestions, especially by those experienced in shooting 24 bore rifles.

With kind regards,
Jani
