[BProckets] BP mix for #20 rockets

[Joseph Madziarczyk]

I would say air float too, but I had thought that at that size maybe he 
was slowing down the mix with a mixture of air float and coarse 
charcoals.

I have tooling for a 2"id bp rocket and was going to press out a couple 
this weekend. Since the bore is close to his, 2 1/4", I wanted use a 
mix closer to the 20# than a 6#.
