300 Whisper load data out of Sierra manual
I went a little differnt route and built a Savage based on the 7.62x25 Tokarev. I could use surplus ammo in a pinch. Decent factory ammo was available. Dies are cheap, brass is readily available. I loaded mine mostly with heavy stuff at subsonic levels but could have ramped it up pretty easily. Mine was a neat project that a lot of people liked shooting.
The manual lists a few loads using the powders you have in the velocity range you are looking for so you should be good.
