An apparatus (18) for reducing the diameter of an open end of a container (16) is claimed. The apparatus (18) comprises a housing having a longitudinal axis (135). A die (130) is supported in the housing about the longitudinal axis. A radially expandable pilot member (140) is also supported in the housing. The radially expandable pilot member (140) is selectively moveable between a contracted position and an expanded position relative to the longitudinal axis (135). The radially expandable pilot member (140) comprises a plurality of forming members (150a-d). A method which utilizes the apparatus (18) is also claimed.
