NOT Flake! This is a severely flattened sperical powder! You can tell because the spheres were not same size and when they went through roller to flatten, some when flatter than others, causing different shapes. Flake powders are pretty round, and uniform. A lot can fit into a case. More than you will ever need. This makes this powder more dangerous if you make a reloading error.
Cleaner than Titegroup and similar in performance. Not as economical though, since you need slightly more powder in the case, and the price of HP38 is slightly more. This is a great faster burning powder, fantastic. We look forward to the "fast burning powder" showdown to see if this thing can win! It has to be up there..its just a SOLID performer! you cannot go wrong with this powder. Its everything you could want in a faster burning 9 MM Pistol powder...really.
