MikeM,
Remembering ... I Believe ... your comment about doing "living History" demonstrations, you should be aware, those "old" hand loading tools were intended for loading Black Powder. Black Powder is very forgiving of errors. For all practical purposes, you can't get enough 2 or 3f BP in a cartridge to blow up a SA revolver. Smokeless on the other hand .... is very UNFORGIVING. IF you screw up with Smokeless, I refer you to the photographs provided by the good Professor Marvel.
We often see You Boob "heroes" whom try to make a U-Boob featurette and it's obvious our "Hero" is clueless. Before you get in front of and audience, I would suggest an amount of practice with your tools. Say, around 500 or so rounds. If you can't do it in your sleep in a dark room with someone screaming in your ear, your not really ready for "Prime Time."
Give some serious thought to planning for your plan. The best plan only survives to the first shot. Having a half loaded round ignite in front of a discerning audience will NOT enhance your image.
