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 very 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 9 MM, you do not want this powder, as you could accidently put too much in a case and go far beyond book recommended pressures
