This is 45 ACP Winchester Ranger Bonded 230gr. Hollow Point Ammo. This ammo features the new Winchester Ranger Bonded bullet that is manufactured using a newly developed proprietary bonding process. This process eliminates the limitations of traditional copper plated bullets. Ranger Bonded has a controlled jacket thickness and taper, along with a unique bonding process that bonds the copper jacket to the lead core. This is done to ensure optimum performance. The resulting permanent core/jacket bond, with the special hollow point cavity, act in unison to control expansion with deep penetration. This maximizes performance and weight retention through a variety of the toughest barriers – especially auto glass. This ammo is packed in 50rd. boxes.
