Nosler Partition Bullets for Sale in USA

Nosler Partition Bullets for sale in usa at good prices, Shop now at Ammunitionsolution.com. The bullet that started the company, Nosler Partition Bullets feature a fully tapered jacket that ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet’s axis controls expansion and curls the jacket uniformly outward at high or low velocities.

Nosler’s integral Partition supports the expanded mushroom and retains the rear lead alloy core. The enclosed rear core retains more than half the original bullet weight for deep penetration. The special crimp locks in the rear core section, adding strength to resist deformation under the pressure of heavy magnums. This is not loaded ammunition.

What is Nosler Partition Bullets?

Nosler Partition 7mm bullets are among the most trusted and respected hunting projectiles in the industry, renowned for their innovative dual-core design and outstanding terminal performance. Designed for serious hunters who demand deep penetration, controlled expansion, and reliable accuracy, these bullets have set the benchmark for premium hunting ammunition for over 75 years.

Key Features of Nosler Partition 7mm Bullets

• Dual-Core Construction:
  The hallmark of the Partition bullet is its patented dual-core design. It features two lead cores separated by a solid copper-alloy partition. The front core expands rapidly upon impact, creating a massive wound channel and transferring devastating shock to the target. Meanwhile, the rear core remains intact to maximize weight retention and penetration, even through bone and tough tissue. This ensures ethical, deep kills on medium to large game.

• Fully Tapered Copper-Alloy Jacket:
  The jacket is engineered to be thinner at the tip for reliable expansion and thickens toward the rear to protect the rear core. This design controls expansion and prevents bullet deformation, especially when fired from high-velocity magnum cartridges.

• Flat Base and Spitzer Tip:
  Most Nosler Partition 7mm bullets, such as the 140-grain and 160-grain variants, feature a flat base for stability and a spitzer (pointed) tip to enhance ballistic efficiency and accuracy at longer ranges.

Popular 7mm Partition Bullet Weights and Applications

• 140 Grain Partition:
  Ideal for medium-sized game, the 140-grain bullet offers a balance of velocity, expansion, and penetration. It is suitable for cartridges like the 7mm-08 Remington and lighter 7mm magnums, delivering consistent performance at moderate ranges.

• 150 Grain Partition:
  Offering a slightly heavier projectile, the 150-grain bullet provides improved sectional density and penetration, making it a versatile choice for a wide range of game and cartridges.

• 160 Grain Partition:
  The 160-grain bullet is a favorite among hunters pursuing larger game such as elk and mule deer. It excels in cartridges like the 7mm Remington Magnum and 7mm Weatherby Magnum, providing deep penetration and controlled expansion even at high velocities.

• 175 Grain and Heavier:
  For the largest and toughest game, heavier Partition bullets in the 175-grain range and above ensure maximum penetration and energy transfer, suitable for long-range shots and magnum cartridges.

Ballistic Performance and Accuracy

Nosler Partition 7mm bullets are engineered for excellent accuracy and ballistic efficiency. Their spitzer design and consistent manufacturing result in tight groups and reliable trajectories. For example, the 160-grain Partition has a G1 ballistic coefficient around 0.475 and a sectional density of 0.283, enabling flat trajectories and retained energy at extended ranges.

Hunters report sub-MOA accuracy in many rifles loaded with Partition bullets, making them a top choice for precision hunting where shot placement is critical.

Terminal Performance and Ethical Hunting

The dual-core design ensures that the bullet expands reliably at virtually all impact velocities, even at longer ranges where velocity drops. The front core’s rapid expansion creates a large wound channel, while the rear core’s retention guarantees deep penetration to reach vital organs.

This combination results in quick, humane kills with minimal meat damage, fulfilling the ethical hunting mandate. Whether hunting deer, antelope, elk, or wild boar, Nosler Partition 7mm bullets deliver consistent, devastating terminal performance.

Summary Table

How does the Nosler Partition bullet perform in different weather conditions?

Nosler Partition bullets perform reliably across a variety of weather conditions due to their robust design, but certain factors related to velocity and environmental influences can affect their behavior.

Controlled Expansion in Various Conditions

The Nosler Partition’s patented dual-core design—with a front core engineered to expand rapidly and a rear core that retains weight for deep penetration—ensures consistent performance even when environmental factors change. The front core reliably mushrooms and fragments to create a large wound channel, while the rear core maintains about 60% of the bullet’s mass for penetration, which is crucial for ethical kills.

Impact of Velocity and Temperature

Performance can vary depending on the bullet’s impact velocity, which in turn is influenced by weather conditions such as temperature and humidity. For example, colder temperatures can reduce muzzle velocity slightly, potentially affecting expansion. However, Nosler Partition bullets are designed to expand effectively over a wide velocity range, maintaining terminal performance even at longer ranges or in cooler climates.

Stability and Accuracy in Wind and Atmospheric Conditions

The Partition bullet’s aerodynamic shape and consistent manufacturing deliver excellent in-flight stability, which helps maintain accuracy in windy or variable atmospheric conditions. Hunters and shooters report that Nosler Partition bullets hold their trajectory well, minimizing wind drift and drop, which is essential when shooting in unpredictable weather.

Considerations on High-Velocity and Twist Rates

There have been reports that very high velocities (2600-3200 fps) combined with fast barrel twist rates can cause jacket-core separation issues in smaller calibers, but this is less common in typical hunting calibers and velocities where Nosler Partitions excel. For most 7mm and larger calibers operating within ideal velocity ranges (1900-2400 fps impact velocity), the bullets perform flawlessly regardless of weather.
