Are the 300 AAC Blackout, 300 Whisper, and the 300 Fireball "interchangable" to some extent?
Are the 300 Whisper and the 300 fireball essentially the same cartridge that just gets around the copyright of the "whisper" name?
I read (on the internet

) that the 300 AAC has a longer throat so it would allow the 300 whisper to be shot in a weapon chambered for the 300 AAC...
