And... how is this supposed to be better than a normal Slug?  Fosters, Brenneke, or Sabot?  Accuracy looks highly inconsistent and I'm really not getting the application for these that would give more desirable results over existing options.   
The Penetration potential is interesting, yes.  But Federal already has penetrating slugs that I would bet would deliver better results. 
And if you need more penetration that that, Son, a Shotgun isn't the weapon of choice.
