[BProckets] BP mix for #20 rockets

[Doug]

If my memory serves me correctly, from his video, he grinds his own, and then mills his BP for several hours, at which point he adds his own 80 mesh to the mix.  Assuming he has not changed his procedure.  I will look at the video again and verify tonight.
