Hello all

Hope some can help me out.

I am seeking around for my first BP rifle, but I don't know so much about them.
Can these two calibers be used today, legally, for hunting?
I guess they will be just right for games up to large deer, hog, bear, moose and so. Same goes for light games in Africa.

Or?
How is it to find brass and bullets?
The old 11*60R is interesting, have seen a old S/S hammer for sale, and got really warm in my heart...But, todays use?

All help is good for me

Have a good day all
