A fine flattened spherical powder. 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.
This is a similar powder to Ramshot True Blue, but takes more powder to achieve similar velocity.
This is a far above average versatile powder for 9 MM and a good overall choice. It meters very easily because its so fine. It is not on a dirty powder, by comparison. It can do higher velocity loads, although it is nowhere near the best choice for +P or +P+, as True Blue, CFE Pistol, or Silhouette would be superior in that regard.
This is simply a middle of the road powder for 9 MM. A good overall choice for most tasks except perhaps 9MM MAjor, where there would be no reason to use this powder at all.
