Designed to deliver devastating terminal ballistics from today's compact personal defense handguns/pistols and utilizes a solid copper hollow point bullet (projectile) which offers barrier blind" performance and is engineered to penetrate the toughest barriers at varied ranges and velocities.Even as the bullet travels through tough destructive barriers such as glass drywall metal and/or fabric nearly 100% bullet weight retention is achieved hence the term "barrier blind".The all-copper bullet construction expands reliably into five sharp edge cutting petals delivering deeper penetration than standard lead-core bullets.This ammunition produces low perceived recoil and delivers high-velocity accuracy for quick follow-up shots.Caliber: 40 S&WBullet Type: Solid Copper Hollow Point (SCHP)Bullet Weight: 130 grMuzzle Energy: 449 ft lbsMuzzle Velocity: 1247 fpsRounds Per Box: 25Boxes Per Case: 40Casing Material: BrassHazair: Yes"
