So I bought some Pyrodex P the other day only to discover shortly thereafter that it isn't supposed to be that good for making quickmatch (according to PyroUniverse).
But since I already had it, I experimented a bit and it seems to me it works just fine. In fact, the 10" length I tested took off like a little rocket.
Formulation: Pyrodex P/dextrine solution on cotton string in 1/8" heatshrink.
Anyone else tried this? Seems a good alternative to BP-based quickmatch.
