This is a flattened shrerical powder. Its uses are mainly for high velocity loads we would summarize. Looking closely at it, it doesn't look very spherical, it looks like a creek bed of pebbles. Its fairly dense. You can put more in a case than you would ever want. This makes this powder potentially unsafe if you make a loading mistake. In performance, it is similar to other top velocity powders, such as Winchester Autocomp, 3N37, or Silhouette. Except versus the Sil & 3N37, it will need over a grain less to achieve similar velocity with this powder.
If you are just learning how to reload 9MM, you do not want this powder, as you could accidentally put too much in a case and go far beyond book recommended pressures
