Any ideas where I can get a mold to make these "caps" ?

It looks like a partial operation of making a bullet using 22cal hulls for jackets and not running them through the point fo Remington die! If that is any help

another thought, try contacting Ron Blackmond. He makes first rate dies and presses that use to be very reasonably priced.
