The Nosler Partition bullet has a long-standing reputation for reliability and consistent performance, particularly in hunting situations demanding deep penetration and controlled expansion. The 160-grain 7mm Partition is no exception. This bullet has earned its place among serious hunters seeking reliable game-taking power, making it a popular choice for a wide range of animals. This in-depth analysis will explore the characteristics, performance data, and ideal applications of the Nosler Partition 160 grain in 7mm caliber.
Understanding the Nosler Partition Design
The key to the Nosler Partition's success lies in its unique construction. Unlike many other hunting bullets, the Partition features a two-part design:
- Forward Core: A hard, lead-alloy core designed for deep penetration. This core maintains its weight and integrity even after expansion, ensuring maximum transfer of energy to the target.
- Rear Partition: A softer lead-alloy section that separates from the core upon impact. This controlled expansion creates a large wound channel, increasing the lethality of the shot.
This ingenious design provides a powerful combination of penetration and expansion, making it effective on a wide variety of game, from deer to elk and even larger animals depending on the rifle and shot placement. The bonded core prevents fragmentation and ensures consistent performance, even at longer ranges.
Comparing the 7mm 160 Grain Partition to Other 7mm Bullets
| Bullet Type | Weight (grains) | BC (G1) | Expansion | Penetration | Ideal Game |
|---|---|---|---|---|---|
| Nosler Partition | 160 | 0.470 | Controlled | High | Deer, Antelope, Elk, Larger Game (with proper shot placement) |
| Nosler AccuBond | 150 | 0.500 | Controlled | Moderate | Deer, Antelope, Elk |
| Barnes TTSX | 168 | 0.520 | Controlled | Moderate-High | Deer, Antelope, Elk, Larger Game |
(Note: BC values and expansion characteristics can vary slightly depending on the velocity and impact conditions. This table offers a general comparison.)
The table highlights that while the Nosler AccuBond boasts a higher ballistic coefficient (BC), giving it a slight edge in long-range accuracy, the Partition prioritizes deeper penetration, a critical factor for larger or tougher game. The Barnes TTSX represents a different technology altogether, excelling in penetration and expansion without lead. The choice depends heavily on the hunter's priorities and target game.
Ballistic Performance of the 160 Grain 7mm Partition
The 160-grain 7mm Partition performs exceptionally well across a range of velocities. Its relatively high sectional density contributes to deep penetration, and the controlled expansion ensures consistent energy transfer to the target. Typical velocities from common 7mm cartridges like the .280 Remington, 7mm-08 Remington, and 7mm Remington Magnum will vary, but real-world results consistently show significant penetration and expansion.
- High Penetration: The solid core of the bullet ensures deep penetration, even through bone, vital for ensuring a clean and humane kill.
- Controlled Expansion: The partitioned design leads to controlled and reliable expansion, creating a large wound channel without excessive fragmentation.
- Consistent Performance: The bullet's robust construction translates to consistent performance across various conditions and shooting distances.
Real-World Case Study: Elk Hunting with the 7mm 160 Grain Partition
Several hunters have reported successful elk hunts using the 7mm 160-grain Partition. One such example involved a broadside shot at approximately 200 yards using a 7mm Remington Magnum. The bullet penetrated completely through the elk, exiting cleanly, leading to a quick and humane kill. The substantial energy transfer ensured the elk was dropped quickly and efficiently.
Ideal Applications and Game
The 7mm 160-grain Nosler Partition is a versatile bullet suitable for a broad range of hunting situations:
- Deer: Provides excellent performance, ensuring clean kills even on larger bucks.
- Antelope: Ideal for this agile and fast-running game. The Partition delivers consistent performance with sufficient energy transfer for quick kills.
- Elk: The bullet's deep penetration and controlled expansion are essential for effectively hunting larger game like elk. Accurate shot placement remains paramount.
- Other Medium to Large Game: The 7mm 160 grain Partition can be used effectively on other medium to large game such as boar, depending on shot placement and the power of the rifle used.
Important Note: While effective, the choice of bullet always depends on several factors, including the specific cartridge, rifle, hunting conditions, and the hunter's proficiency. Always consult ballistics tables and hunting guides for appropriate bullet selection.
Conclusion: A Reliable Choice for the Serious Hunter
The Nosler Partition 160-grain 7mm bullet stands as a testament to proven design and consistent performance. Its unique two-part construction provides the ideal balance of penetration and expansion, making it a reliable choice for hunters seeking confidence in their ammunition. Whether hunting deer or elk, the 7mm 160-grain Nosler Partition is a bullet that serious hunters can depend on for reliable, ethical harvests. Remember to always prioritize safe and ethical hunting practices.
