A flake powder. Quite bulky.   However, this burns very fast, so it will be more than you will ever need in a case.  This makes this powder more dangerous if you make a reloading error.  Doesn't look like Alliant Red Dot does it.  These are like pringles chips huh?  They make us hungry!  LETS EAT!! 

Those HAP groupings is no human error, every shot on the board is aimed with precise 3 MOA red dot to within ~.1" accurate, and the gun is leveled on each shot.

Here are some of the loads we tried with this powder..
