Roy and Kutter and others, I think you are on the right track. I just dug out this seating tool [pictured along side the item in question] . It comes with one of those heavy hexagonal barrel muzzle loading target rifles. Obviously made for that rifle which is a concoction of a Golcher lock and a barrel that appears to have been on another gun.
