Abstract: A projectile for firearms comprises a body defining a generally cylindrical base portion opposite an ogive. The body further defines a longitudinal axis. A plurality of pairs of adjacent flutes are defined in the ogive. Each flute has a radius of curvature which decreases along the longitudinal axis from a leading edge to a trailing edge of the flute. The adjacent flutes of each pair define and are substantially symmetrical about a central ridge. Each ridge is coplanar with the longitudinal axis and has a lesser depth than a bottom surface of each flute relative to a curved outer surface of the ogive. Each ridge has a radius of curvature which decreases along the longitudinal axis from an origin to a terminus of the ridge. The decreasing radius of curvature of the flutes prevents the projectile from over penetrating human-sized soft tissue targets without sacrificing energy transfer to such targets.
