I used a 22. I did not use any bait just a long distance call lure outside the trap, a food lure on a stick in the back of the trap, a bird wing hanging in the back of the trap and a few feathers on the floor of the trap. If you use feathers or a wing make sure the trap is covered up good so the feathers can not be seen from above(sight exposed bait).
