Choosing the right ammunition for big game hunting is critical. Two bullets consistently rank among the best: the Hornady InterLock and the Nosler Partition. Both boast exceptional performance, but their designs and resulting characteristics lead to subtle—and sometimes significant—differences in their application. This in-depth comparison will help you decide which bullet best suits your hunting needs.
Understanding Bullet Construction: Key Differences
Both the Hornady InterLock and the Nosler Partition are renowned for their ability to deliver consistent penetration and controlled expansion in tough game, but their construction differs substantially. Understanding these differences is crucial to appreciating their performance nuances.
Hornady InterLock: A Classic Design Refined
The Hornady InterLock features a cannelured design, with a unique interlocking ring around the base of the bullet. This ring is crimped into the case, ensuring reliable bullet seating and preventing separation from the cartridge during firing. The jacket is relatively thin, allowing for reliable expansion. The bullet's core is a lead alloy, and it's designed for controlled expansion, aiming for deep penetration and a large wound channel.
Key Features of the Hornady InterLock:
- Interlocking Ring: Prevents bullet separation.
- Cannelure: Facilitates crimping and consistent seating.
- Controlled Expansion: Balances penetration and expansion.
- Reliable Performance: Proven track record across various game species.
Nosler Partition: A Legendary Choice for Deep Penetration
The Nosler Partition boasts a more complex construction. It's built with a lead core partitioned into two sections by a heavier, harder lead alloy core, surrounded by a gilding metal jacket. This ingenious design creates exceptional penetration even in the toughest animals. The front portion expands reliably, while the rear section usually remains intact, ensuring deep penetration, even through bone.
Key Features of the Nosler Partition:
- Partitioned Lead Core: Maximizes penetration, even with bone shots.
- Durable Construction: Retains weight and integrity for deep penetration.
- Reliable Expansion: Consistent expansion even at high velocities.
- Superior Performance: A longtime favorite among serious hunters.
Performance Comparison: On the Range and in the Field
While both bullets perform admirably, subtle differences emerge in their ballistics and terminal performance.
Penetration and Expansion: A Tale of Two Bullets
The Nosler Partition generally offers superior penetration, especially in heavy-bodied game or when shots encounter bone. The partitioned core ensures a significant portion of the bullet continues to penetrate deeply, even if the front section expands considerably. The Hornady InterLock, while offering good penetration, may exhibit more deformation and expansion, resulting in a potentially larger wound channel but potentially less overall penetration in extremely dense game.
| Bullet | Penetration | Expansion | Wound Channel |
|---|---|---|---|
| Hornady InterLock | Good | Moderate to High | Relatively Large |
| Nosler Partition | Excellent | Moderate | Moderate to Large |
Velocity and Trajectory: Subtle Differences
Velocity and trajectory differences between the two rounds are largely dependent on the specific cartridge and load. Generally, differences are marginal and may not significantly impact shot placement at typical hunting ranges. However, at longer ranges, the subtle ballistic differences might become more noticeable.
Choosing the Right Bullet: Game and Hunting Style Considerations
The best bullet depends on your specific hunting needs and the game you're pursuing.
Hornady InterLock: Ideal for:
- Medium-sized game: Deer, antelope, and similar-sized animals.
- Hunters prioritizing large wound channels: Faster kills are sometimes associated with larger wound cavities.
- Hunters wanting a more affordable option: Hornady Interlocks tend to be more cost effective.
Nosler Partition: Best suited for:
- Large and dangerous game: Elk, moose, bear, and other thick-skinned animals.
- Hunters prioritizing deep penetration: Essential for ensuring a clean kill, especially with difficult shots.
- Hunters seeking maximum penetration in tough situations: This is the bullet's strength.
Conclusion: No Single "Best" Bullet
Both the Hornady InterLock and the Nosler Partition are exceptional big game hunting bullets. The "best" choice ultimately depends on the type of game you're hunting, your hunting style, and your personal preferences. Thorough research and consideration of these factors will ensure you select the bullet best suited to your needs, resulting in a successful and ethical hunt. Remember to always consult your firearm's manual and follow safe hunting practices.
