There was also a BlackDot in a 10oz bottle that never got to market and BlackMagXP.
It appears they more or less bought the name than the formula but i don't have the original MDS for a comparison. If its by the pound and cheaper than BH209, i really want to give it a try in the 45s.

Looks like its easier to ignite by 70F.
777 MDS

About 100F less needed for ignition

It says under the description "water resistent". So I am assuming the ignition would be related to what is being used to protect the product from moisture.
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.
