The Sierra 1520 Varminter 85 GR Spitzer bullets are designed with this philosophy at their core, offering a unique blend of attributes that make them highly desirable for a variety of shooting applications.

Who Are These Bullets For?

• Varmint Hunters: If your passion involves ethically culling pests like coyotes, prairie dogs, foxes, or groundhogs, these bullets offer the perfect blend of accuracy and terminal performance to ensure clean, humane kills, even at extended ranges. The Spitzer design facilitates a flat trajectory, crucial for hitting small targets.
• Precision Target Shooters: Reloaders seeking to push the boundaries of their .243 Winchester or other 6mm rifles will find the inherent accuracy of Sierra bullets invaluable. These bullets are capable of producing sub-MOA groups with proper load development.
• Experienced Handloaders: Those who understand the nuances of reloading and are looking to customize ammunition for specific rifles and shooting conditions will appreciate the consistent manufacturing quality of Sierra bullets, which simplifies load development.

What Problems Do These Bullets Solve?

• Inconsistent Accuracy: Many factory-loaded ammunition options or lower-quality bullets can lead to frustratingly wide shot groups. Sierra Varminter bullets are known for their exceptional concentricity and weight uniformity, leading to improved accuracy.
• Poor Terminal Performance: For varmint hunting, a bullet needs to expand rapidly and effectively to ensure a quick, ethical dispatch. The Spitzer design and construction of the 1520 are optimized for this purpose within the velocity parameters of the .243.
• High Trajectory Issues: When engaging small targets at varying distances, a flatter trajectory minimizes the need for significant holdover adjustments. The aerodynamic Spitzer profile of the Sierra 1520 helps maintain velocity and reduces bullet drop.
• Limited Customization: Handloaders often feel constrained by factory ammunition. These 85-grain Spitzer bullets provide the foundation for crafting custom loads tailored precisely to your rifle's preferences and your specific shooting needs.

The Engineering of the Spitzer Design: A Deep Dive into Sierra Model 1520

The term "Spitzer" refers to a bullet with a pointed nose, designed to reduce air resistance and improve aerodynamic efficiency. This design is foundational to the performance of the Sierra 1520, contributing significantly to its flat trajectory and retained energy downrange.

Key Attributes of the Sierra 1520 Varminter Spitzer

1. Aerodynamic Profile: The sharp, pointed nose reduces drag, allowing the bullet to maintain velocity over longer distances. This translates directly into a flatter trajectory and less wind deflection, both critical for precision shooting at various ranges.
2. Boat Tail Option (If Applicable to 1520): While the primary description notes Spitzer, many precision bullets, including some Spitzer designs, also incorporate a "boat tail" at the rear. This tapered base further reduces drag, especially at trans-sonic and supersonic velocities, enhancing stability and accuracy. (Note: The 1520 is a flat base spitzer for maximum bearing surface in bore and stability, which contributes to its renowned accuracy at typical varmint ranges).
3. Lead Core and Copper Jacket: Sierra bullets are meticulously constructed with a precisely formed lead core encased in a seamless copper jacket. This construction provides the optimal balance of integrity for bore ride and controlled expansion upon impact.
4. Exceptional Concentricity: Sierra is renowned for its stringent manufacturing tolerances. The concentricity (how uniformly round and balanced the bullet is) of their Varminter bullets is outstanding, which minimizes wobbling in flight and ensures consistent accuracy.
5. Weight Retention vs. Expansion: For varmint bullets, the goal is often rapid, almost explosive expansion to incapacitate the target quickly. The 85-grain Spitzer is engineered to deliver this effect within the typical velocity range of the .243 Winchester, fragmenting effectively inside the target to transfer energy rapidly.

Optimizing Your .243 Reloads with Sierra 1520

Reloading with Sierra 1520 bullets offers an unparalleled opportunity to fine-tune your ammunition for peak performance. Here’s what you need to consider:

Selecting the Right Powder and Primer

• Powder Choice: The .243 Winchester thrives with medium-burn-rate rifle powders. Common choices that pair well with 85-grain bullets include IMR 4064, Hodgdon Varget, H414, or Winchester 760. Always consult a reputable reloading manual (such as those from Sierra, Hornady, Speer, or Lyman) for precise starting and maximum load data.
• Primer Selection: Standard large rifle primers are typically used for the .243 Winchester. Experimentation with different brands (e.g., CCI, Federal, Remington) can sometimes yield subtle improvements in accuracy, though consistency is often more important than brand-specific "magic."

The Importance of Overall Length (OAL) and Crimp

• Cartridge Overall Length (COAL): Finding the optimal COAL for your specific rifle and bullet combination is crucial for accuracy. This involves determining the bullet's "jump" to the lands of the rifling. Small adjustments (often in increments of .005 inches) can significantly impact group sizes. Always ensure your chosen COAL fits within your rifle's magazine and does not exceed SAAMI specifications.
• Crimp: For most bolt-action rifles, a light crimp or no crimp is preferred to avoid deforming the bullet. If using a tubular magazine or a semi-automatic rifle where bullet setback could be an issue, a slight taper crimp might be considered, but generally, the neck tension provided by proper sizing is sufficient.

Ballistic Performance of the 85 Grain .243 Spitzer

The 85-grain weight is often considered a sweet spot for the .243 Winchester, especially for varminting and medium-range target shooting. It offers an excellent balance of velocity, kinetic energy, and ballistic coefficient.

• Velocity: Depending on your barrel length and powder charge, 85-grain bullets can achieve muzzle velocities typically ranging from 3,000 to 3,300 feet per second (fps).
• Kinetic Energy: This high velocity translates to substantial kinetic energy, ensuring rapid and effective energy transfer upon impact, which is vital for quick, humane kills on varmints.
• Ballistic Coefficient (BC): While specific BC values vary slightly between manufacturers and precise bullet designs, the Spitzer profile of the Sierra 1520 generally provides a good BC for its weight class. A higher BC means the bullet sheds velocity less rapidly, resulting in a flatter trajectory and less wind drift, improving accuracy at longer distances.

Field Performance: From Benchrest to Prairie Dog Town

How does the Sierra 1520 perform in real-world scenarios? Its design shines in applications where precision and reliable terminal performance are paramount.

Coyote Hunting

When hunting coyotes, you often encounter shots ranging from close quarters to several hundred yards. The Sierra 1520's accuracy ensures you can place shots precisely, even at extended ranges. Its rapid expansion helps anchor coyotes quickly, minimizing tracking. The flatter trajectory helps simplify holdover calculations, especially in dynamic hunting situations.

Prairie Dog and Groundhog Extermination

For high-volume varmint shooting like prairie dog extermination, consistency is key. The Sierra 1520 provides the reliable accuracy needed for repeated hits on small targets. The explosive terminal performance is also highly effective, ensuring the target is dispatched cleanly. Its relatively lighter weight compared to hunting bullets for larger game makes it an excellent choice for minimizing fur damage on smaller furbearers if pelts are a consideration, though its primary design is for rapid energy dump.

Competitive and Recreational Target Shooting

While not explicitly a match bullet, the Sierra Varminter series offers exceptional accuracy for its class. For shooters looking to practice fundamentals, develop loads, or engage in informal target competitions, the 1520 provides a cost-effective way to achieve sub-MOA precision from a .243 rifle. It's an excellent choice for developing confidence in your rifle's capabilities.
