Alliant Bullseye
This is a fast burning powder.  It is on the end of the spectrum of 9MM with Titegroup, N320, Cleanshot, Sport Pistol, and others.  This makes this a good choice for certain kinds of shooting for 9MM and also economical

Not bad.  Go look at outside of case for Titegroup to see a dirty case on outside..this is nowhere near that level of dirty

A flake powder.   A fast Flake powder so one must be extra careful when loading 9MM with it.  A small error can result in a dramatic increase in pressure.  For this reason is why we do not recommend this type of powder, or any faster powder for learning how to reload 9MM.  Start with Blue Dot instead, way better choice to learn reloading 9MM. 
This powder is also on the dirty side.  It is dirty like Titegroup in ways. Take a look at the cases compared to other powders.. 
Lets take a look at some of the brass...

Here are some of the target loads we shot...Some of these loads are over book published load values and just because they worked for us, does not mean they will eb safe for you...do not load over manufacturer book maximums.
Note some of the loads were far more accurate than average.   The 147 grain, 3.3 load, that was 1 hole, and perhaps, the most accurate load of any powder tested.  All of the loads are pretty accurate.
We prefer this powder over Titegroup, but still think its too dirty.
