Oncet Upon a Time,
MMaybe 30 years ago my center fire Wzard of California sent, as a joke, I believe, a powder tester. I can;t remember if it was Flintlock or Percussion. where you would put in a fixed amount of powder, Close it with a spring loaded cover and fire it to see how far the cover was propelled along a curved arc marked with numbers..
Difficult to describe.
Now with so many substitutes for the original BP a device like this might becoming of some value.
It originally was used to compare genuine black powder from different manufacturers..
Now it would be used to compare different substitutes
I haven't seen an ad for one of these in decades but I think they might bear resurrection.
When I was forced, as a public service , to quit shooting there was Goex and Pyrodex and a peculiar powder from South America originally intended for fireworks not ML that was quite dirty,
Today I see references to all sorts of stuff BlackMZ being the most recent.
If anyone has such a curiosity in their collection, Mine disappeared, now would be a good time to bring it out and do a comparison study.
On the other hand, If there is another way to do comparisons of the relative strength of the various products I would like to hear about it. Swiss powder appeared after my exit and is generallyregarded as being an appreciably more zippy than Goex. But has anyone every figured out a way ro measure this?
Enquiring minds want to know, at least this one does.
