I forgot to mention, if the erasers you buy are too thin when you press them out with a 357 or 44 magnum shell, you can glue two erasers together with barge cement and they will stick together pretty well. You'll get the hang of it. Just keep pluggin' away at it. HA-HA-HA-HA-HA !!! Boy, it doesn't take much for me to amuse myself.
