Welcome aboard Templar.
Lots of data in the reloading sub-forum.
With H322 under the 100gr Sierra, you can start with 26.0gr and work up to 27.9gr. Sierra has published data for that.
Hodgdons data went up to 29.0gr Compressed under the 100gr Nosler Ballistic Tip, which is quite a bit more than Sierras data for the 100gr HP.
Sierras data for Benchmark under a 100gr HP starts down at 25.6gr and works up to 29.5gr.
Sierra used Hornady cases and Winchester SRPs.
Hodgdons used Lapua cases and Federal 205M SRPs.
