Bullet SHOT is a Hofzinser's ace routine done in a different way.

A card is selected, signed, and shuffled into the deck. You introduce four aces with a different colored back with holes in them. The aces slowly tell you what the card is. You are able to guess the suit of the selected card and you tell them to focus on the hole; with a shake the hole multiplies and it's exactly the same value of the selected card. Hold your applause, not only did you guess what the card is, you've actually found their signed card in between the aces; you turn over the card it's their signed card. You leave them an impossible object that they can keep and remember forever.
