Alexander Arms Relinquishes Trademark on 6.5 Grendel; Cartridge Adopted by SAAMI

What makes the .300 Blackout preferable to the .300 Whisper?  Both are based on the .221 Fireball.  I think shoulder angle is different, but other than that I don't know of other differences.  The Whisper should go in an AR as well as a Blackout?

No Whisper is made from 221 fireball cases where blackout comes from 5.56/.223. So to answer your question on what makes Blackout better is the brass is about 70% cheaper for blackout.

So basically, the Blackout is a .308 short and the only difference from the standard AR 15 are the chamber and bore dimensions ?

SWEET ! 

No, really Remington 30AR is really a .308 short, Blackout is really .223 fat. It uses a .223 bolt where the Rem 30AR uses a .308 bolt.

Either way you want to phrase it you get a far more versatile carbine that can use the same projectile as your long range rifle and the only non stock item is the barrel. Bolt, mags etc are all standard "off the shelf" items and it saves a little room on the reloading bench since you only need 1 type bullet.

Definitely, if you already shoot AR15's you probably want to stick to the blackout since you'd have the parts interchangeability but if you're an AR10 shooter you may want the Remington 30AR since you should be able to use the same bolt and some other parts.
