A Closer Look at the Nosler Ballistic Tip Design
The Nosler Ballistic Tip bullet represents a culmination of decades of ballistic engineering. The design is rooted in the desire to create a bullet that combines flat trajectories, consistent expansion, and exceptional accuracy. This goal is achieved through a series of carefully considered design features.
The defining characteristic of the Ballistic Tip is, of course, the polymer tip itself. This distinctive feature isn’t just for aesthetics; it plays a crucial role in enhancing the bullet’s overall performance. The tip is meticulously engineered to initiate and control expansion upon impact. It is constructed with a specific polymer blend that is matched to the bullet weight, intended use, and ballistic profile. Upon impact, the tip initiates expansion, acting as a wedge to force open the hollow cavity within the bullet’s nose.
Beyond the polymer tip, the Ballistic Tip incorporates a boattail design. This design tapers the base of the bullet, effectively reducing drag. The boattail shape creates a smoother airflow as the bullet travels through the air, improving the ballistic coefficient. This characteristic contributes to flatter trajectories and reduced wind drift, both highly desirable qualities for long-range shooters.
The jacket and core are also crucial elements. Nosler typically employs a thin jacket, designed to allow for controlled expansion while maintaining sufficient structural integrity. The design allows for rapid expansion, creating a larger wound channel in the target.
All these features work together, to deliver consistent and predictable results. The combination of these features is designed to maximize long-range accuracy and provide devastating on-game performance, allowing the bullet to transfer kinetic energy effectively while still having enough structural integrity to reach its target and penetrate through tissue and bone.
Unveiling the Specifications: What Makes This Bullet Tick
The **7mm 120 Grain Nosler Ballistic Tip** holds a special place in the 7mm cartridge family because of its balance of weight and performance. These specifications are not arbitrary; they determine the performance characteristics of the bullet.
The weight of the bullet, precisely 120 grains, contributes to its overall ballistic profile. The weight is light for the 7mm caliber, so the bullets typically travel at high velocities, contributing to a flat trajectory and increased energy on impact.
The bullet’s diameter, 0.284 inches (7.21 mm), is the standard for 7mm cartridges. This consistency contributes to the bullet’s versatility in many different 7mm cartridges, from the small 7mm-08 Remington to the powerful 7mm Remington Magnum.
The ballistic coefficient, a crucial indicator of a bullet’s ability to overcome air resistance, is typically a value higher than most other bullets within this range.

These specifications work in concert to produce a bullet that delivers a combination of velocity, downrange energy, and accuracy, making it a compelling choice for various hunting and shooting applications.
Performance in Action: The Ballistics of Effectiveness
To truly understand the **7mm 120 Grain Nosler Ballistic Tip**, one must examine its performance in action. While specific ballistics data will vary based on the cartridge used and the specific load, some generalizations can be made. It’s always crucial to consult reliable ballistics calculators and reloading manuals for exact information.
When loaded in a 7mm-08 Remington, this bullet can achieve muzzle velocities in the range of 2900-3100 feet per second (fps). In the 7mm Remington Magnum, those velocities can increase to around 3100-3300 fps. The initial muzzle velocity significantly impacts the trajectory. The higher the muzzle velocity, the flatter the trajectory, and the less the bullet drops over longer distances. This, in turn, means less holdover is required when shooting at distance.
The energy at the muzzle is directly related to the velocity and weight. As the bullet travels downrange, the energy decreases due to air resistance. This bullet design is made to hold onto as much energy as possible, making the projectile more effective at longer ranges.
The ballistic coefficient allows the bullet to resist wind drift. This is crucial, especially for longer-range shots. A bullet with a high ballistic coefficient is less affected by the wind and is more likely to hit its target.
