Understanding the Dillon 550 Reloading Press
Overview of the Dillon RL550 Press
The Dillon RL550 press is a mainstay in reloading setups worldwide, praised for its durability, speed, and user-friendliness. Its design embodies progressive reloading principles, allowing multiple stages of the reloading process to occur simultaneously with each stroke of the handle. This streamlined workflow significantly boosts efficiency compared to single-stage presses, making it ideal for those who shoot frequently.
The core of the Dillon 550’s operation hinges on its ingenious indexing system. This system automatically rotates the shell plate, advancing each cartridge case through the various stations. This progressive action includes the initial sizing and priming of the brass, powder dispensing, bullet seating, and the crimping stages.
The press’s frame is constructed from rugged materials, built to withstand the rigors of repeated use. Its solid construction contributes to the Dillon 550’s stability, ensuring accurate and consistent reloading. The press’s design is also deliberately made to be easy to maintain, a feature that contributes to its long lifespan.
One of the key features of the Dillon 550 is its modularity. It’s designed to be easily adapted for different calibers, a capability that’s significantly enhanced by the use of conversion kits.
What is a Dillon 550 Conversion Kit?
Defining the Conversion Kit
The term “conversion kit” in the context of the Dillon 550 describes a set of parts specifically designed to enable the press to handle different cartridge case sizes and shapes. When you decide to reload a different caliber, you’re not simply changing one thing; you’re adjusting the dimensions of the parts that hold, size, and shape the brass cases and apply the bullets. That’s where the conversion kit comes in.
Key Components
A Dillon 550 conversion kit typically consists of three primary components. The shell plate is the most visually noticeable change. This is the circular metal plate that holds the cartridge case, and its design varies according to the rim and base diameter of the cartridge. The shell plate securely holds the case as it progresses through the different stations of the reloading process.
The second critical component is the powder funnel. This piece fits into the powder measure and precisely directs the measured amount of powder into the case mouth. Different calibers often require different powder funnel profiles to accommodate the varying neck diameters of the cases. This ensures that the powder is dispensed correctly and prevents spillage.
Finally, certain conversion kits include a case feed tube. Though not always required, a case feed tube simplifies the process of feeding cases into the press. This addition is commonly seen in kits for pistol calibers and helps improve the loading speed.
These components, meticulously engineered and adapted, work together to ensure the reloading process is successful and precise, allowing you to load different calibers quickly and reliably.
Benefits of Using Dillon 550 Conversion Kits
Enhanced Versatility
The ability to reload a broad spectrum of calibers with a single press is the standout benefit. Whether you’re looking to load .223 Remington for your AR-15, 9mm for your pistol, or something entirely different, the appropriate conversion kit facilitates the process. This flexibility eliminates the need to purchase and store multiple presses, each dedicated to a specific cartridge. It simplifies your reloading bench and streamlines the overall process.
Cost-Effectiveness
Buying a single Dillon 550 press and various conversion kits is often considerably less expensive than investing in several specialized presses. This cost savings are particularly appealing for reloaders who plan to load a variety of calibers, as it minimizes the financial investment.
Ease of Use
Dillon understands that reloaders value efficiency. Changing calibers with the conversion kits is designed to be a straightforward process. The components are typically installed without any complex tools, and the switch can be completed in a matter of minutes. This swift caliber change significantly reduces downtime and makes reloading sessions more productive.
Dillon’s Reputation
Dillon Precision has built a reputation for manufacturing high-quality, dependable reloading equipment. Dillon conversion kits are designed and manufactured to the same exacting standards. This ensures a product that is built to withstand consistent use and provide the performance and longevity that reloaders demand. The Dillon guarantee and availability of replacement parts further enhance the value.
Choosing the Right Conversion Kit
Identifying Your Calibers
First, define the calibers you intend to reload. Create a list of the cartridges you plan to load, whether it’s pistol cartridges, rifle cartridges, or a combination of both. This is the foundation for your selection.
Understanding Compatibility
Research the cartridge compatibility for your Dillon 550 press. The information on Dillon’s website or in their product manuals is the definitive guide. This chart is an invaluable resource, outlining which conversion kits are required for various calibers and identifying any additional components that might be needed.
Selecting Kits for Specific Needs
Depending on your shooting habits and the calibers you’re loading, you might opt for specific kits. For instance, if you intend to load a high volume of pistol rounds, a kit that includes a case feed tube is advantageous. Conversely, if you primarily focus on rifle cartridges, a case feed tube might not be as crucial. Also, consider the bullet diameters and shapes for each caliber. Make certain that the powder funnel, shell plate, and other components properly accommodate these dimensions.
Considering Used Kits
Used Dillon 550 conversion kits can be an economical option. However, carefully inspect the components for any signs of wear and tear. Ensure the shell plate’s surfaces are in good condition, that the powder funnel is free of damage, and that all parts are present and functional.
