I'm the same as Phil, I've got 200g but not fully tested it yet. From one small test I do know already that it does not ignite from a naked flame or when open and with a piece of blackmatch. I understand that even confined it needs a hot primer or fuse, I have tested and know that a simple visco fuse is not enough to light a firecracker size test. I'm thinking a spollette with a hot burning comp may be required or you may need to add some sulphur to the usual al/KCOL4 mix to sensitise slightly.
I will do a small test with a hot comp in a spollette this weekend I think.
"Through smaller salutes using ten grams and even less of flash powder can be made to function, the supplier recommends BA for use in salutes containing 15 grams or more of flash powder. It is ideal for aerial salutes for 25 mm and larger sizes."
