Are you looking for 9mm major or 38 super major data?

I use it on occasion for 38 super, but don't want to give you 38 super data if you are looking for 9major.

Lots of info about HS-6 for for making major if you search in the 9mm/.38 caliber reloading section.

Agreed. Search the mentioned section and you'll find enough data to keep you busy reading quite a while !

For 38 Super here is what use:

Powder: ww540/HS-6

OAL: JHP = 1.235", FMJ/CMJ = 1.250"

Either SPP or SRP primers

115gr MG w/ 9.8 gr yields about 168 PF

124gr MG w/ 9.0 gr yields about 168 PF

Shot out of a 5.4" Schuemann barrel with 3 ports.

9.4 gr HS-6 with a 125 gr plated flat point .357 bullet in a Tanfo V12 makes 170 pf for me.

9.4 gr with Montana 121 gr IFP is 168-9 pf in same gun.

It took 9.9 gr with a 115 TMJ bullet to just barely make major in same gun.

This is all in 38 Super Comp brass with CCI rifle primers.
