The Dillon 550B is a legendary reloading press, known for its versatility and robust build. But its capabilities can be further enhanced with conversion kits, allowing you to reload a wider variety of calibers and cartridge types with ease. This guide dives deep into Dillon 550B conversion kits, exploring their benefits, types, and how to choose the right one for your needs.
Understanding Dillon 550B Conversion Kits
A Dillon 550B conversion kit fundamentally changes the press's configuration to accommodate different calibers. This usually involves replacing key components like the powder measure, case feeder, and dies. This allows you to efficiently switch between calibers without significant adjustments, saving you valuable time and effort.
Key Components Often Included in Conversion Kits:
- Powder Measure: Different calibers require different powder charges. Conversion kits often include a powder measure specifically calibrated for the target cartridge. This ensures accurate and consistent powder dispensing.
- Case Feeder: The case feeder is a crucial component of the 550B's high-speed operation. Kits will often include a new case feeder or components to adapt the existing one for the new caliber. This ensures smooth and reliable case feeding.
- Dies: Dies are the heart of the reloading process. Conversion kits usually supply the necessary dies for sizing, expanding, and seating bullets in your chosen caliber. These dies are typically specifically designed for optimal performance with the 550B.
- Other Components: Depending on the kit and caliber, you might find other components, such as shell plate conversions, indexing adjustments, or specific tooling for unique cartridge designs.
Types of Dillon 550B Conversion Kits
Dillon offers a vast array of conversion kits covering a wide range of popular pistol and rifle calibers. The available kits are often categorized by the specific cartridge they are designed for. You'll find kits for common calibers like 9mm, .45 ACP, .223 Remington, .308 Winchester, and many more.
Finding the Right Kit: Key Considerations
Choosing the right kit hinges on understanding your specific reloading needs:
- Caliber: This is the most obvious factor. Ensure the kit explicitly supports your desired caliber.
- Cartridge Type: Consider whether you're reloading pistol or rifle cartridges, as different kits are designed for each type.
- Brass Type: While many kits are versatile, some are optimized for specific types of brass (e.g., bottle-neck vs. straight-walled).
- Kit Completeness: Review the kit's contents carefully. Some may include only the essential components, while others offer a more comprehensive package.
Benefits of Using Conversion Kits
Investing in a Dillon 550B conversion kit offers significant advantages:
- Efficiency: Switch between calibers quickly and efficiently without extensive adjustments.
- Accuracy: Kits often come with components calibrated for your specific caliber, ensuring accuracy.
- Cost-Effectiveness: Over time, reloading can significantly reduce ammunition costs. Conversion kits enhance this cost savings by enabling you to reload various calibers.
- Versatility: Expand your reloading capabilities without needing multiple presses.
