Anyone using HS-6 in 9mm with 115gr. FMJ ? What's your charge ?

9mm HS-6 115 gr book loads are 6.1 to 7.0 gr, or they were 18 years ago when I was doing 9mm testing.

In a Kel-Tec P11 the work up is ok up to 10.5 gr with RP brass.
10.8 gr the primer may pierce
11 gr the primer always piercing
11.5 gr the primer pierces and the case bulges down the feed ramp.

Note that most powders cannot fit enough powder in a 9mm case to make trouble with 115 gr bullet. But HS-6, 3N37, and AA#5 are exceptions.

Within a tenth or two of the top load for your bullet listed at www.hodgdon.com seems to work rather well with HS6 in 9/38/357/40/44/45 acp.

HS-6 / Win 740 same powder, different label.

Natoreloading.com is a great site for 9mm handloading.
