I own a 44-shot shotgun. It belonged to my dad and was purchased about 1912. It is a break-open action and is a model 101 Stevens. Some people have had it bored out to take the 2-1/2 inch .410. About as fool-hardy a stunt I have ever heard of. I also have two old 44-shot cartridges and they have a bell-like end. I heard from a young man who also has one and he has hand-loaded empty 44-40 brass. I could too but the barrel is badly pitted and wouldn't pattern well.
