Thread hijack sort of- can either the whisper or the blackout be easily formed from .223 brass?
I assume these are running real fast twists?
Yup. Cut the 223 back to 1.355 or so and form a short neck.
Most 300s use an 8 twist barrel to shoot the heavy subsonic ammo.
Here is a picture.

Here's another comparison of 300BLK vs 5.56.

The ONLY difference between a 5.56 rifle and a 300BLK is the barrel. Same bolt, same magazines, etc. As you can see in the above picture both rounds are loaded into PMAGs.
The current Hodgdon 2012 Annual has some data for .300 Blackout. Thankfully, they are able to correctly describe what JD Jones has on the .300 Whisper, e.g., a trademark. Something even JD Jones can't get straight (writing in American Handgunner that he had "copyrighted the cartridge", which is nonsensical ).
From what I understand and please correct me if I'm wrong, the Whisper can work in a 300 but be careful about shooting a 300 Blackout in the Whisper chamber. Like shooting 556 in a 223 chambered gun.
