What am I looking at here? Is this a spherical head pin? Used to drift the case halves apart?

If so, next time (you may rebuild one for a friend) put a inverted cone shape on the drift. Use a piece of cold-rolled rod the diameter you want and face drill it for the inverted cone shape. And radius the circumference of the face on a stone wheel.
