The chart above is for the Hodgon powders though Accurate 1680 is used by some on other loads. Also not shown on the chart are the 245 grain cast lead bullets some of us use for sub-sonic speeds below 1050 FPS. I really like the 300 Blackout loads in the really heavy weights for up close and personal home defense and out to 150 yards for chunking lots of lead in the AR15 platform, but there are much better calibers/loads for past 150 yards in my opinion. For sub-sonic supressed loads or close in shooting it is a versital platform.
PS- You can shoot 300 Whisper rounds in a 300 Blackout chamber but you cannot shoot 300 Blackout rounds in a 300 Whisper chamber.
