The .243 Winchester, a popular round for deer hunting and varminting, often benefits from the right bullet choice. The Nosler Partition 100-grain bullet is a frequently discussed option, known for its reliable performance and consistent expansion. This in-depth article will explore the Nosler Partition .243 100 grain bullet, examining its design, ballistic performance, applications, and overall suitability for various hunting scenarios.
Understanding the Nosler Partition Bullet Design
The Nosler Partition bullet's unique design is its key feature, setting it apart from many other hunting rounds. Its construction involves a lead core encased in a gilding metal jacket. The crucial element is the partition, a thin, lead-free metal separating the lead core into a forward and rear section. This partition plays a vital role in maintaining bullet integrity upon impact.
How the Partition Works
- Impact and Expansion: Upon impact, the bullet's forward section expands reliably, creating a large wound channel. This delivers immediate stopping power.
- Partition's Role: The partition prevents the bullet from completely fragmenting. The rear section remains intact, penetrating deeply even through dense bone or tough hide.
- Consistent Performance: This dual-action ensures consistent performance across a range of game sizes and shot placements. The bullet reliably retains a significant portion of its weight, maximizing penetration.

| Core | Lead |
| Jacket | Gilding metal |
| Partition | Thin, lead-free metal separating the core |
| Design Benefit | Controlled expansion, deep penetration, and retained weight despite expansion |
Ballistic Performance of the 100-Grain .243 Partition
The 100-grain Nosler Partition in .243 Winchester delivers impressive ballistic performance. Its relatively high ballistic coefficient (BC) contributes to excellent long-range accuracy and retained energy downrange. However, exact ballistic figures will vary depending on the specific rifle's twist rate, barrel length, and ammunition manufacturer's load data. Consult your specific ammunition's package for precise data.
Typical Ballistic Performance (Approximate): (Note: These are estimates and can vary)
- Muzzle Velocity: ~2900 fps
- Muzzle Energy: ~1700 ft-lbs
- 100-yard Velocity: ~2500 fps
- 100-yard Energy: ~1250 ft-lbs
- 200-yard Velocity: ~2100 fps
- 200-yard Energy: ~900 ft-lbs
These values highlight the bullet's effectiveness at moderate to extended ranges.
Ideal Applications for the Nosler Partition .243 100 Grain
The Nosler Partition .243 100 grain is a versatile bullet suitable for a wide range of hunting situations. Its characteristics make it particularly well-suited for:
- Deer Hunting: The bullet's controlled expansion and deep penetration provide excellent performance on deer-sized game. It is effective on both whitetail and mule deer, offering reliable kills even with less-than-perfect shot placement.
- Medium-Sized Game: The bullet's power is adequate for animals like coyotes, and smaller game species, although other bullets might be a better choice for such scenarios.
- Hunting at Moderate Ranges: The bullet's ballistic characteristics make it suitable for shots out to 250-300 yards with appropriate skill and equipment. Beyond this distance, wind drift can become more significant, requiring careful compensation.
Case Study: A Successful Hunt with Nosler Partition .243 100 Grain
A hunter recounts using a Nosler Partition .243 100 grain bullet to harvest a mature whitetail buck at 200 yards. The shot was taken slightly quartering away, striking the buck's shoulder. The bullet passed through the animal, leaving a significant blood trail, resulting in a quick and clean kill. The hunter noted the bullet's predictable expansion and deep penetration, which contributed to the successful hunt. This experience highlights the bullet's reliability and performance in a real-world hunting scenario.
Considerations and Alternatives
While the Nosler Partition .243 100 grain offers many advantages, it's essential to consider some factors:
- Cost: Nosler Partition bullets are generally more expensive than other hunting bullets.
- Game Size: While effective on deer, its capabilities for larger game might be limited; for elk or moose hunting, a heavier caliber and bullet is advisable.
Alternatives include the Nosler Ballistic Tip, renowned for its long-range accuracy and expansion, or the Barnes X-Bullet, known for its excellent penetration and minimal expansion. The choice depends heavily on your specific hunting needs and preferences.
Conclusion: A Solid Choice for the .243 Winchester
The Nosler Partition .243 100 grain bullet remains a popular and effective choice for hunters seeking a reliable, controlled-expansion bullet for medium to moderately-sized game. Its partition design assures consistent performance, deep penetration, and controlled expansion. While cost is a factor, the bullet's overall performance and reliability often justify the price for hunters who prioritize accuracy and predictable results. However, careful consideration of shot placement and understanding of ballistic limitations is vital for successful and ethical hunting.
