I took a look at the propellant in the Firestick and compared it to BH209 during the last few days. They look exactly the same.
Today I found the SDS sheet for the Federal Firestick. It contains Nitrocellulose and Guanidine Nitrate (corrosive) and Potassium Perchlorate (corrosive), which are the same chemicals found in BH209.

If we compare this to the SDS sheet for Blackhorn 209 the truth is revealed.
The propellant used in the Firestick is the same thing as BH209.
I cannot understand why anyone would think corrosive chemicals need to be used in this cartridge, since the burn-rate and mass of propellant can be carefully controlled by the manufacturer??? The pressure could be easily controlled without the corrosive chemicals.
