Why Handload Your Own Ammunition for the .270 WSM?

Reloading, or handloading, offers a myriad of benefits that factory ammunition often cannot match. For the discerning shooter using cartridges like the potent .270 WSM, these advantages are even more pronounced:

• Unparalleled Accuracy and Consistency: Factory ammunition is mass-produced to general specifications. Handloading allows you to meticulously control every variable: powder charge, bullet type, primer choice, and seating depth. This level of precision translates directly to tighter groups on the target and more predictable ballistic performance in the field. Imagine custom-tuning a load specifically for your rifle's barrel harmonics!
• Significant Cost Savings: While there's an initial investment in equipment, reloading drastically reduces the per-round cost of ammunition, especially for specialty cartridges like the .270 WSM. Once you factor in the cost of primers, powder, and bullets, you'll find that premium-grade handloads are often cheaper than budget factory rounds. The ability to reuse expensive brass multiple times is a major contributor to these savings.
• Customization for Specific Applications: Are you hunting deer, elk, or smaller game? Are you shooting long-range targets or competitive precision matches? With handloading, you can select the perfect bullet weight and design for your intended purpose, optimizing for expansion, penetration, or ballistic coefficient. You can also adjust velocity to suit different ranges or rifle twist rates.
• Availability and Self-Sufficiency: In times of ammunition shortages, relying on factory production can leave you sidelined. Having the ability to produce your own ammunition provides peace of mind and ensures you can continue shooting when others cannot.
• Educational and Rewarding Experience: Handloading is a fascinating blend of science and art. Understanding the components, the ballistic principles, and the meticulous process involved is deeply rewarding. Many reloaders find immense satisfaction in creating their own high-performance ammunition.

Understanding the RCBS Full Length Die Set: What Does It Do?

The RCBS 31301 Full Length Die Set is engineered to perform the critical operations necessary to transform a fired cartridge case back into a precision-ready component. Unlike neck sizing dies, which only resize the case neck, full-length sizing dies resize the entire case body, including the shoulder and neck, returning it to factory dimensions. This is crucial for ammunition that needs to cycle reliably in semi-automatic or lever-action rifles, or for brass that has been fired in a different chamber. A standard RCBS two-die set, like this one, typically includes:

1. Full Length Sizing Die: This is the workhorse of the set. Its primary function is to return the spent brass case to its original, factory-specified dimensions. This involves:
   • Resizing the Case Body: Compressing the case walls back inward to ensure it fits properly in any SAAMI-spec chamber.
   • Resizing the Case Neck: Reducing the diameter of the case neck to securely hold a new bullet.
   • Decapping: A decapping pin removes the spent primer from the primer pocket.
   • Expanding the Case Neck: An expander ball, typically part of the decapping rod, gently expands the case neck to the correct internal diameter, ensuring proper bullet tension and concentricity without overworking the brass.
2. Bullet Seating Die: This die is used to accurately seat the new bullet into the resized and primed case, and in some designs, apply a crimp.
   • Bullet Seating: The bullet is guided precisely into the case mouth, and its seating depth is controlled by adjusting the die. Consistent seating depth is paramount for accuracy.
   • Crimping (Optional/Adjustable): Many seating dies also allow for a crimp to be applied. A crimp secures the bullet more firmly in the case, which can be important for cartridges used in tubular magazines, heavily recoiling firearms, or to improve powder burn consistency. The .270 WSM, being a powerful rifle cartridge, often benefits from a light crimp.

The .270 WSM Cartridge: A Modern Powerhouse

The .270 Winchester Short Magnum (.270 WSM) is a high-performance, short-action magnum rifle cartridge introduced by Winchester in 2002. It quickly gained popularity among hunters and long-range shooters for its impressive ballistics, combining flat trajectory with significant energy delivery.

• Ballistic Prowess: The .270 WSM fires a .277-inch diameter bullet at high velocities, typically ranging from 3,000 to 3,300 feet per second, depending on bullet weight and barrel length. This translates to a very flat trajectory, making it excellent for long-range engagements without excessive holdover.
• Energy and Knockdown Power: With excellent energy retention, the .270 WSM delivers substantial knockdown power, making it highly effective for a wide range of medium to large game, including deer, elk, and bear, within reasonable hunting distances.
• Short Action Advantage: Being a "short magnum," the .270 WSM fits into short-action rifle platforms, which are generally lighter, more compact, and allow for faster cycling than long-action rifles.
• Versatility: The cartridge's ability to handle various bullet weights (from 130-grain to 150-grain and heavier) allows reloaders to tailor loads for different game or target shooting scenarios.

Reloading for the .270 WSM requires precision due to its magnum pressures and bottleneck design. The RCBS 31301 Full Length Die Set is perfectly suited for this task, ensuring that every case is sized back correctly for safe and consistent firing in your rifle.

Step-by-Step Benefits for Your Reloading Process

Using the RCBS 31301 Full Length Die Set seamlessly integrates into your reloading workflow, providing tangible benefits at each stage:

• For Case Preparation:
  • Effortless Sizing: The full-length sizing die efficiently returns fired cases to SAAMI specifications, crucial for consistent chambering and preventing feeding issues in your .270 WSM rifle.
  • Reliable Decapping: The integrated decapping pin quickly and cleanly removes spent primers, preparing the primer pocket for a fresh primer.
  • Optimized Neck Tension: The expander ball ensures proper neck tension, which is vital for holding the bullet securely and consistently, contributing to better accuracy.

  • Precise Seating Depth: The bullet seating die allows for precise adjustment of seating depth, letting you fine-tune your overall cartridge length (COAL) to optimize for your specific rifle's chamber and desired accuracy.
  • Concentricity Control: The design of the seating die promotes excellent bullet concentricity, minimizing "wobble" and ensuring the bullet travels straight down the bore, which is paramount for achieving tight groups.
  • Adjustable Crimp: While optional, the ability to apply a controlled crimp with the seating die adds an extra layer of security, particularly useful for hunting loads or cartridges subjected to heavy recoil.

Achieving Optimal Results with Your RCBS 31301 Die Set

To maximize the performance of your RCBS 31301 Full Length Die Set and produce the most accurate .270 WSM ammunition possible, consider these best practices:

1. Clean Your Brass Thoroughly: Before sizing, clean your cases to remove carbon, powder residue, and any abrasives. Tumbling or ultrasonic cleaning are effective methods.
2. Lubricate Cases Properly: Full-length sizing requires proper case lubrication to prevent cases from sticking in the die and to reduce stress on your press and the brass. RCBS Case Lube or similar products are essential. Apply a thin, even coat.
3. Set Up Dies Correctly: Follow the instructions provided with your die set and reloading press for proper die adjustment. Correct setup is critical for consistent results and to prevent damage to your dies or brass.
4. Monitor Case Length: After sizing, always trim your cases back to the specified trim-to length. The .270 WSM, being a bottleneck cartridge, will stretch with firing and sizing. Over-length cases can cause dangerous pressure spikes.
5. Develop Loads Systematically: Always start with published load data from reputable sources like RCBS, Hornady, Speer, or Hodgdon. Begin with starting loads and work up incrementally, watching for pressure signs. Never exceed maximum published loads.
6. Maintain Your Dies: Keep your dies clean and free of rust. A light coat of gun oil after use, particularly on the decapping pin, will prolong their life. Store them in the included plastic case when not in use.
