[QUOTE="sable tireur, post: 2836169, member: 27307"] The Bondstrike cross-section from Norma: [ATTACH type="full"]468909[/ATTACH] [I]The core of the Bondstrike is a precision-formed lead that's been chemically bonded to its copper jacket. This creates a tough bullet intended to perform reliably and maintain integrity when encountering heavy muscle tissue and bullet- busting bone. Rather than fragmenting or shedding petals, a bonded bullet housing a solid lead core has to be designed so that it expands during penetration and loses minimal weight. As tough as bonded bullets are for use on heavy bodied big-game, durability can come at a price if expansion is compromised at lower terminal velocities. That's where tipped bullets shine. The Bondstrike's blue polymer tip is designed to initiate expansion on impact as it's forced rearward into the lead core. At extreme close distances expansion is violent, which can be detrimental if the bullet fragments upon impact. However, the Bondstrike design mitigates that splashing effect. When combined with the shape of the Bondstrike's ogive and boattail, the polymer tip also increases the bullet's ballistic coefficient (BC), which is advertised at an impressive .615 across the .30-caliber, 180-grain lineup.
