Abstract: A bullet designed to expand reliably at subsonic velocities has a front end region divided by notches into petals and a groove on its exterior surface. Each notch may be separated into a notch forward segment and a notch rear segment by a discontinuity. Each notch may be cut with a depth such as to provide a web of material extending along a portion of the length of a central cavity.

Abstract: A bullet designed to expand reliably at subsonic velocities has a leading end region divided by notches into petals. The exterior of the bullet has a groove configured to allow limited initial bending of the petals to facilitate spreading of the petals to increase the cross-section of the bullet upon impact with a target.
