I was wondering if a person could do something like this in an Encore/bolt. A smaller charge of a pistol powder. I'm thinking this would be a more quiet combo?

Very cool. Will the Whisper loads translate directly to the Blackout?

I am not sure about bulk density, but their burn rates are reported to be very close:
