I know that this is probably technically a no-no, but people duplex BPCR rounds with smokeless and bp all the time. Why not a little 777 or pryodex to light off BH209? I have half a jug of the stuff that I am no longer shooting because hang fires make my blood pressure rise to far, and I would love to burn it up. Can anyone give me a good reason not to pour 10 grains of 777 and then 90 of bh209 down my barrel?
