- 1. A method of uniformly notching an upsetting non-fragmenting jacketed hollow point projectile for pistol ammunition which method comprises the steps of:
- (a) inserting a lead core forwardly into a rearwardly opening cuplike aluminum jacket to form a jacketed core having a longitudinal axis;
- (b) forming said jacketed core into a projectile preform having the base of said jacket cup facing forward and forming a flat circular frontal area on said projectile preform the frontal area being orthogonal to the longitudial axis;
- (c) simultaneously with said preforming step, uniformly notching but not splitting said flat front of said preform while leaving the ogive of said preform unnotched;
- (d) axially recessing the nose of said jacketed preform to produce a hollow point cavity; and
- (c) forming said notched preform into a final projectile by reducing the flat front of said notched preform so that said notches extend from the ogive, pass over an annular nose rim of said projectile and terminate in said cavity, whereby to produce a bullet which uniformly upsets without fragmentation upon target impact.
