Flake powder. Looks like Alliant Bulleye somewhat. 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.
With so many good powders, does this one stand above in the top tier category? We have just begun. Check Fast Powder testing summary for more tests to find the winner... Anyway, you can't go wrong buying this powder for minor, shooting steel, shooting recreationally, or any other purpose for having fun. It is not, however, the best suited for self defense loads if you want high velocity.
