Alliant Blue Dot
One of the slowest burning powders that can be used in 9 MM.  Produces very high velocities for standard pressure loads
new Xtreme Brass with ~12.72 Capacity. This powder takes up a lot of space! 

Hornady brass as more capacity than other brands on average. This is 10 grains used for a Speer Gold Dot 90 grain bullet. It compresses just fine to 1.075 OAL

10 grains inside a case that holds max ~10.5 grains of Blue Dot (without compressing)

This is a flake powder.  This is one of our favorite powders for 9MM.  Do not load over max book for pressure as it can be unsafe.  If there is such a thing as a "more safe" powder for loading 9 MM, this would win.  With this powder, it takes a lot more time to compress enough powder into the case to make pressures potentially very unsafe.  We loaded up way over book, and came nowhere near the higher pressures in other powder loads.  Nothing is impossible, but we think you can't "double" charge this powder.  We think this could be the best powder on the market for perhaps somebody just learning how to reload 9 MM, due to its case capacity limitations, which is inherently safer if you make a loading charge mistake.
This powder is similar to Power Pistol in that it makes fireballs out the front of the barrel. 
For loading standard or +P Pressure, this would be a top choice, as it produces some of the highest velocities on the market.   It is also decent accuracy accurate.  It has no real downside other than its its below average versatility, since its on the slower end of the powder range.  It was also accurate with lower charge loads made for steel plate shooting, or plinking. 
If this powder had a weakness, it is that the standard deviation & Extreme spread of shots in a string with the same load are above average. 

If you are just learning how to reload 9 MM, buy this powder first, you probably can't do better to start out with.

It is no wonder "other" powder manufacturers are trying to copy this powder.   For casual, recreational reloading and shooting in general?  We think it is hard to do better than this. 
So...what about Blue Dot and what do some cases look like?
 
  • Winchester Case 13.25 grn capacity
  • CCI 500 Primer
  • 8.4 grains
  • 1.095 OAL
  • 124 Grain Precision Delta HP
  • 1360 FPS
  • For such a powerful load, those primers look pretty good.  Blue Dot is great for high velocity

  • That red rimmed case in back is for comparison, it is 4.6 grains using 147 grain 1.145 Xtreme RN, very low power load

Some loads are above any manufacturer data.  Load at your own risk.  What we load doesn't mean it will be safe for you. Do not load above recommended manufacturer book maximums.

Accuracy is just fine.  This is with a Springfilend XD(M) with Venom Red Dot @ about 5 yards.  Some loads were good accuracy and top tier velocity. 

The three loads on bottom right, 124 grain 1365 FPS and the 1475 FPS 90 grain Speer gold Dot?  Without super high pressures?  That is not common.  Look at the accuracy of the upper left steel shooting load.  

We put in 2 HS-T +P commercial loads for comparison.    Blue Dot is far, far more accurate & higher velocity than "most" commercial bought anything. 
Scroll down to bottom of page to see some super hot loads with this powder. 
That 1700 FPS 90 grain load didn't blow primers, bulge the case unusually, or hurt the gun.  We shot many rounds of it and the recoil was harsh as it had more energy than most +P 45 ACP rounds.   This powder can do pretty much anything you want except in very light bullets say, under 90 grain, because you can't fit enough powder in the case.
