A finer flake 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 powder looks like BE86 and a few others. This could make it more dangerous if you get mixed up and change powders often. So be careful. In our opinion, we like the "green dot/red dot/blue dot" concept because you easily know what you are loading and its much harder to get powders mixed up. Perhaps better marketing would have been "BLACK DOT" as in, "in the black"? We are just messing with you Alliant, we love your lineup of powders, one of our favorite companies.
This is a solid performing powder, with good case fill, as the company claims. However, its not that clean, is it? its all relative to other powders, and relative to Titegroup, its a lot cleaner. But compared to D032 from Lovex or Accurate #2? Its not nearly as clean. its middle of the road clean perhaps. Its not super sooty, or like that, so its totally fine.
It meters OK, not as good as perhaps Accurate #2, or D032, or W244, or other ball powders. But its just fine.
