Hygroscopic properties were my biggest complaint with T-7 powder. Those properties are why I swore off the T-7.

So IMO, the question about this new powder would be how is it treated(or what is it treated with) to give it a "water resistant" property??

Obviously "water resistant" is not "water proof". So I wonder what the trade off is??

And certainly this trade off is what is causing the inconsistency of ignition on most other powders?? So I wonder how this powder will differ in the ignition characteristics?? As noted by the ignition temperature in the above post??

So I wonder how the hygroscopic properties of this new powder stack up against the hygroscopic properties of T-7?? And against the hygroscopic properties of the BH-209 that so many of you speak so highly of?? VS plain old Black Powder?? Tom.
From Western powder:

Blackhorn 209 is virtually non-hygroscopic. Changes in temperature or humidity do not affect performance. Blackhorn 209 will not setup or degrade like some other propellants. Shelf life is essentially unlimited.
