BXR Rapid Expansion Matrix Tip is designed specifically for use on whitetail, blacktail, mule deer and antelope. The proprietary matrix tip design allows for high downrange velocity and energy retention while also initiating rapid positive expansion. The jacket and tip combination yields precision accuracy, rapid energy transfer and generates massive knockdown power.FeaturesRapid Expansion – BXR provides the energy transfer and massive knockdown power you can expect from the Best There Is in Deer ammunitionMatrix Tip – Proprietary Matrix (copper/polymer) initiates rapid expansion, tip fragments on impact to present a large expanding hollow-point, resulting in improved ballistic coefficient with added on-target energy transferRapid Expansion – Designed specifically for whitetail, blacktail, mule deer, and antelope. Expansion energy is efficient and effectively transferred on targetSpecificationsCaliber: 30-30 WinchesterBullet Weight: 155 grainType: Bonded Rapid-Expanding Hollow-PointVelocity at Muzzle: 2390 fpsVelocity at 200 Yards: 1743 fpsVelocity at 500 Yards:
