A powder-based projectile for small caliber ammunition including a jacket having an open end, a core disposed within the jacket adjacent the closed end thereof and a heat and pressure resistant barrier disc disposed distally of the core adjacent the open end of the jacket. A portion of the length of the jacket at its open end is inwardly folded in overlying relationship to less than all of the barrier disc to engage and cover a portion of the barrier disc and lock the barrier disc and core within the jacket and to maintain the barrier disc in position to protect the core from heat and pressure resulting from the ignition and burning of gunpowder. A method for the manufacture of the projectile is disclosed.
