And Stay Back

And Stay Back is a perk in the Fallout: New Vegas add-on Dead Money.

Effects
While using a shotgun, you have a 10% chance, per pellet, to knock an enemy back. Note that this perk actually knocks down the enemy rather than sending them flying as the description suggests, similar to Super Slam for melee attacks.

The weapons affected by this perk are the same as those affected by the Shotgun Surgeon perk, namely:
 * Caravan shotgun
 * Hunting shotgun
 * Dinner Bell
 * Lever-action shotgun
 * Riot shotgun
 * Sawed-off shotgun
 * Big Boomer
 * Single shotgun
