Get a block of wood, a wood dowel that just fits inside the shell,a punch to remove primers(an old nail will work) and a hammer. Drill a hole in the wood block, place shell with old primer over hole and punch it out. Place new primer on block, place shell over primer and with dowel inside shell lightly tap dowel with hammer until primer is seated. Now put you powder charge in and whatever wads you use with your blank loads. Seat them using dowel and hammer again. You can run a thin bead of Elmer's glue around the edge of the top wad or card to make it waterproof and keep the load from separating.
