About to start loading both .510 Whisper and .50 Beowulf

[pgg]

My friend and I are about to start loading these both for sub sonic with my AWC can and super sonic. I have a few projectiles and a few suggested loads but no suggested loads for the exact projectiles we have. Would anyone have starting load suggestions for these?

Strong arm ballistics 600 grain beast projectiles For Beowulf and Whisper I hope
Strong arm ballistics 400 grain lead nose Beowulf only
750 Grain Amax for Whisper

Thanks PG

Fill the case up with enough powder to leave just enough room for the bullet.
