  The 9mm's are in Speer brass with the .44's loaded in Starline.

It seems Speer has started utilizing a smaller flash hole in some of their brass.  I know they did this in the 357Sig brass, it is so small it will break the deprimer pins on the deprimers or jam them.  What a PITA  >:(...I made a special depriming pin to deprime them by hand then drill them out to standard size flash holes.  Once they are done no issues! 8)

It will be interesting to see the specs on the 147gr for those velocities, the previous 115's we looked at looked to be AutoComp.  Nothing comes close to those numbers with standard loads listed, because the +P+ is not shown for 9mm.

Hodgdon shows 1522 fps for 24.0 grains of H-110/296 from 8.257" barrel

  The 240's have been improved from past data. We will see!
