Thread: Ulrich Bretscher's SMOKELESS BLACK POWDER & HANDGONNE web page. Re-found!

The smokeless gunpowder is anyway NOT black powder, as it only has two of the three ingredients of BP as defined in our transport regulations. At most it is a safer "BP substitute". What Ulrich Bretscher never tried was making sulfur free gunpowder using the more volatile brown charcoal.

I wonder how the slower sulphur free gunpowder performs in a modern bottleneck cartridge.
