  • BURST CHARGE FOR 2" SPHERICAL SHELLS

    Hi, I am proposing to make 2" spherical shells with green and red stars which have been primed with homemade b.p which is weak. I want to paste the shells with 7 to 8 layers of 3/4" 40 g.s.m virgin kraft paper. Since the b.p I have is not very strong can
    I use H3 packed in a paper roll as a burst charge ? if so how many grams of it can be used ? Can anybody give me some advice on it ? Thanks.

    I use about a gram of flash powder, usually. If I wanted to use H3, I'd granulate it for packing in the burst bag, and use 2-3 grams.
