Buffalo Bore 9mm Luger +P Outdoorsman 147gr Hard Cast Handgun Ammo – 20 Rounds – Buffalo Bore designed this 9mm load, for those people who own a 9mm pistol and wish to carry it in the woods for defense against black bears or even grizzly. This load is designed to penetrate deeply (4 to 6 feet) in a straight line, through flesh and bones and that flat nose does considerably more terminal damage, as it crushes its way through tissues, than a round nose bullet does as it slips and slides its way through tissues and that crushing action, keeps the bullet nose forward and ensures very deep straight-line penetration.
