Nosler Ballistic Tip: Streamlined polymer tip, color-coded by caliber, resists deformation in the magazine, and initiates expansion upon impact; Fully-Tapered Jacket and Special Lead-Alloy Core: Allows controlled expansion and optimum weight retention at all practical velocity levels. The heavy jacketed base prevents bullet deformation during firing; Heavy Jacketed Base: Acts as a platform for a large-diameter mushroom; Ballistically Engineered Solid Base: Boat tail configuration combines with the streamlined polymer tip for extreme long-range performance, and for easier loading
