Bonded bullets have their lead cores fused to the jackets, either chemically or by bonding, so that the two parts are almost inseparable. The Nosler AccuBond utilizes an impact-extruded, gilding metal jacket of solid base design, a lead core that is actually melted inside the jacket, and a polycarbonate tip. Unique to the AccuBond, the base and jacket base walls are very thick, and they become thinner going forward to produce an unusual wider lead core in the forward region of the bullet.
In controlled tests and also in the hunting fields, the AccuBond has proved to expand right down to the base during high-velocity impact while retaining a relatively long shank under normal to low-velocity impact. It has shown a tendency to shed 30 to 40 percent of its original weight, but it penetrates almost as much as the classic Nosler Partition. AccuBond expansion typically runs in the neighborhood of 1.8 calibers, and some writers have gone so far as to say it starts out like a Ballistic Tip and ends up like the Partition.
The AccuBond offers superb accuracy, a high ballistic coefficient, and excellent downrange performance, making it a versatile choice in big-game bullets.
