Daryl and Tinker and Everyone else,

This is all new to me, so I appreciate any comments.

BTW I think I read once that it is not good to use plastic hulls with black powder? That the BP generates too much heat?

Why can't brass shells be used in a 10-bore OR this rifle? Assuming they can be sourced of course.

I have a good idea whom to call about past information on this rifle. Maybe even the guy whom may have restored it.
