The 270 Winchester Short Magnum (WSM) has earned a reputation as a powerful and versatile cartridge, popular among hunters and target shooters alike. To reload this potent round effectively, you'll need a high-quality die set. This guide dives deep into the world of 270 WSM die sets, helping you choose the right one for your reloading needs. We'll cover everything from the components of a typical set to factors to consider when making your purchase.
Understanding the Components of a 270 WSM Die Set
A complete 270 WSM die set typically includes three essential dies:
- Sizing Die: This die resizes the spent brass to the correct dimensions for reloading. It's crucial for ensuring consistent chambering and proper bullet seating. Some sizing dies offer neck sizing only, preserving brass life, while others offer full-length sizing.
- Powder Die: This die measures and drops a consistent amount of powder into each cartridge case. Accuracy in powder dispensing is paramount for consistent velocity and optimal performance. Many powder dies feature adjustable powder measures for precise control.
- Seating Die: This die seats the bullet onto the powder charge, crimping the case mouth if needed. The seating die ensures consistent bullet placement and overall cartridge length. Some seating dies incorporate a crimp feature.
Beyond the Basics: Additional Components
While the three dies above form the core of any set, some advanced sets might include extra components:
- Bullet Seating Stems: Different bullet seating stems accommodate various bullet types and diameters, crucial for proper bullet alignment and seating depth.
- Case Length Gauge: This tool helps measure the overall length of your reloaded cartridges, ensuring they meet factory specifications.
- Primer Seating Tool: This ensures correct seating depth of your primers. Proper primer seating is crucial for reliable ignition.
Choosing the Right 270 WSM Die Set: Key Factors
Selecting the perfect 270 WSM die set requires careful consideration of several factors:
- Brand Reputation: Established brands like Hornady, RCBS, Lee Precision, and Redding are known for their quality and reliability. Research brand reviews before purchasing.
- Die Material: Steel dies are the most common and durable, but carbide dies provide superior resizing performance, extending brass life. Carbide is particularly helpful for resizing tougher brass.
- Type of Sizing: Decide if you need a full-length sizing die or a neck sizing die. Full-length sizing resizes the entire case, while neck sizing only resizes the neck, preserving brass integrity.
- Your Reloading Press: Ensure the dies are compatible with your reloading press (e.g., single-stage, progressive). Different presses might require different shell holders.
- Budget: Die sets range in price from budget-friendly options to high-end, feature-rich sets. Determine your budget before making a purchase.
Case Study: Comparing Two Popular 270 WSM Die Sets

Maintaining Your 270 WSM Die Set
Proper maintenance extends the life and accuracy of your die set:
- Lubrication: Always lubricate your cases before sizing to reduce friction and prevent die damage.
- Cleaning: Regularly clean your dies to remove built-up brass and lubricant.
- Storage: Store your dies in a safe, dry place to prevent rust and corrosion.
