Well, I've made some quite nice flash in my garage with KMnO4 and home made aluminum from foil in the ball mill. I put it at the end of a black powder pile, but I don't have enough to fill a small tube with it. Just finished milling some aluminium foil/can flakes and they're pretty fine, but I've found the larger bits in the powder are jagged, so they are from the can, and if I pick some up in my fingers it will give a greasy sheen.

I think I will pass on cans and just use foil now, mills much much faster too.
And I also don't think I'll be swapping the KMnO4 out of my flash powders because I can't find chlorate and I'm not buying anything from the US. Shipping times are ridiculous and expensive.
