Hodgdon data - 300 BLK
 

Though these are all super-, I'll mention my experience with H110 at subsonic reloading.

I spent a good portion of last year chasing an explanation to the vertical stringing problems I had with a 16" bolt gun whisper.

Through trial and error (and the wisdom of several reloaders), I found that H110 is VERY sensitive to position in the case and to operating temperature - with small variations in these 2 factors causing fairly large variations in my chronographed velocities.

Shooting super, great, have at it; shooting sub-sonic, avoid H110, especially if you shoot in hot climates.

(Lil gun and #9, no such problems, great subsonic performers.)

In my opinion, H110 and Lil'Gun have no place in subsonic 300 AAC BLACKOUT loading for ARs as they don't make enough gas pressure to cycle the action with a gas port size which will also shoot supersonic ammo well. The powders are still good, but I would run them supersonic.
