Description For quality and affordability, Nosler Partition Bullets are outstanding. Nosler Partition Bullets have a fully tapered jacket designed to explode immediately at the mouth of the thin jacket coupled with gradual thickening near the axis that controls expansion while curing uniformly outward at both low and high velocities. These bullets also support the expanded mushroom while retaining the rear core made from lead alloy. In the rear core area are crimp locks that bolster the strength needed to resist deformation from the pressure of heavy magnums.PRODUCT DETAILManufacturer: Nosler Bullet Type: SPT Caliber: .270 Diameter: .277" Grain: 130 gr Rounds: 50 Firearms, trailers, and some accessories are only available for purchase in stores.
