ABSTRACT:
A semi-wadcutter bullet useful for target practice includes a lead core partially contained and locked in a metal cup-shaped jacket. The lead core has a cylindrical body, a frusto-conical nose formed integral with the body and extending forwardly therefrom, and a forward-facing annular ledge formed on the body and surrounding a base of the nose. The metal jacket has a cylindrical sidewall with an annular rim portion thereon. The core body is seated within the jacket sidewall with the core nose protruding thereabove. The rim portion of the jacket sidewall is bent into overlying relation with the ledge on the core body so as to lock the jacket on the core body and define a forwardly-facing sharp profile for making clean cut holes in the target paper. The semi-wadcutter bullet is manufactured first by inserting and seating the core into jacket such that the core body is surrounded by the jacket sidewall up to the ledge on the body and the sidewall rim portion extends slightly above the core body and along the core nose. Then the core nose and jacket sidewall rim portion are deformed respectively to form an annular ledge on the core body surrounding the core nose and to bend the sidewall rim portion into overlying relation with the ledge on the core body locking the jacket on the core body and defining the sharp corner profile on the jacket.
