Ballistic Tip Hunting:In a perfect world, there would be no changing winds, no hunting pressure, no wary, spooked, or running game that might require a fleeting or distant shot. And all it would take to bring down that trophy buck would be a textbook 100-yard broadside shot. Fortunately for us, the real world of hunting is a bit more challenging than that. In fact, the more you hunt, the more you realize how unpredictable and unforgiving nature can be--which is why Nosler engineered the Ballistic Tip Hunting bullet to be very predictable and extremely forgiving. Features:- The Ballistic Tip Hunting bullet's polycarbonate tip 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.- Heavy jacket base acts as a platform for large diameter mushroom.- Ballistically engineered Solid Base boat tail configuration combines with the streamlined polycarbonate tip for extreme long-range performance.Technical Specifications:165 Grain Spitzer (Green Tip)Diameter: .308"Sectional Density: .248Ballistic Coefficient: .475*Sectional Density: The ratio of a bullet's weight, in pounds, to the square of its diameter, in inches.*Ballistic Coefficient: The ratio of a bullet's sectional density to its coefficient of form, used to describe the bullet's effectiveness in overcoming air resistance during flight.Note: These are component bullets, not loaded ammunition.
