I just picked up some PP for loading 40 SW. I am trying it in 9mm.

I notice a big difference in load values between Speer 14 and the new Hornady #8

For a 124gr FMJ RN Speer lists 5.6 to 6.4gr 1.135

Hornady lists 4.3 to 5.7gr for the same weight shape bullet 1.150

Alliant only list for the 124 GDHP at a max of 6.4. 1.120

I put 6.4 grs in a empty case and to me it would be a compressed charge (or almost) when a bullet is seated.

After shooting this powder in the 40 SW it is a flash , bang, LOUD powder. I can not imagine what 6.4 grs in a 9mm would be??

What are powder charges are you all using??
