David alot of the cowboy action guys use the brass shotgun hulls. And alot of them shoot BP in their loads. RCBS is even making a cowboy action set of dies for the all brass shell.
They do not have any real collectors value. But you should still be able to get $20 to $30 for them.
Do you belong to any forums that have some cowboy action shooters?? They would probably be interested in them. Tom.
