Really my point was to help keep flinters, particularly new ones, from wasting money on the "alternatives" and avoid the frustration I had when trying to use Pyrodex in my first flintlock many moons ago.
I can relate to the yucky face stickers, we put them on things in the house when my son was real little. Just as a joke I put one on my lunch bucket, the bride never packed a lunch for me in the last 25 years.
