RRLP (Reduced Ricochet, Limited Penetration) bullets combine accuracy with explosive, on-target fragmentation. They won't come apart in flight, even at extreme velocities, yet won't destroy steel targets. Unlike other frangible bullets, the protective guilding-metal jacket makes them a reliable, sure-feeding choice for autoloading rifles. Both the jacket and powdered copper-tin core are 100% lead-free to comply with lead-free mandates on military- and law- enforcement practice ranges.
