Most manufacturers of personal-protection bullets seek controlled expansion and high weight retention. Not Lehigh Defense; instead, with its aptly named “Controlled Fracturing” (CF) projectiles, the Quakertown, Pa., company prefers preprogrammed separation. Its philosophy is sound, though; multiple, large segments of metal being dispersed increases the likelihood that critical bodily structures and organs are impacted by a single shot. During penetration, hydraulic action shears the CF bullet’s three petals, which rapidly radiate outward while the base offers deep, straight-line penetration. It’s an unconventional but effective design.
