For a really good flash powder you need much finer Al, flake if you can get it (ebay). German dark is best but any fine mesh flake Al will do the job. For nitrate flash I use 5/3/2 KNO3/S/Al. Ideally you need the Al to be smaller than ~400 mesh. The best would be a particle size between 2~15microns. That will give you a great bang with little confinement (or an amazing bang with alot of confinement :P)
Thanks a lot for your reply and advise! I already have German Dark Aluminium, and the only reason why I used the 325 mesh Al, is because I have a lot more and it is a lot cheaper. I also like to experiment with new stuff too :). And besides, if I had wanted to make a great boom, I had made a 70/30 mixture of Potassium Perchlorate and German Dark Aluminium, which I already have on hand ;)
thanks! altho im pretty shure ur pulvurone should lift any small or big shell, whistle mix is risky but if u dont use too much its still good, and was the whistle mix homemade?
I usually only use pulverone or benzolift, but since I had noting laying around, I decided to use only whistle mix. And no, unfortunately and stupidly the whistle was extracted from some small conventional whistles. I DON'T use to split fireworks, but since i bought 100g. of whistle packed in small tubes incl. fuse for about 30 cents I decided to take the chance and do it.
Yeah! It came in a box of 100 whistles with one gram in every single tube. Usually a box costs about four bucks but since it was the 30th of December and the store was not allowed to sell more after NYE, they putted them on sale :D. I bought 25 boxes. In danish currency, the normal price was around 27 DKK and the cheaper price was 2 DKK as i remember. I actually don't remember if it was 2,95 DKK, but that doesn't really matter.
wow u should shoot some of those whistlers out of a mortar, it would be interesting to see! ive done it before tho with my own whistle mix and its pretty fun!
I have actually tried that before, but the whistles didn't ignite. I might wanna add some granulated black powder to the opening for ease of ignition. It's kind of hard for the heat to reach all the way to the powder, since only half the room of the tube is filled with the mix. But I hope that I'll figure out a solution some day :)
Cool

Never ball mill flash powder! You can mill the bp ingredients, but once you add the aluminum your just stupid to mill it.
