The Dillon 550B and 550C are both popular reloading presses known for their reliability and ease of use. But which one is the best choice for you? This in-depth comparison will explore the key differences between the Dillon 550B and 550C, helping you decide which press best suits your reloading needs and budget. We'll delve into their features, capabilities, and ultimately, help you make an informed decision.
Understanding the Key Differences: 550B vs. 550C
Both the Dillon 550B and 550C are progressive reloading presses, meaning they complete multiple steps of the reloading process with each pull of the handle. However, some crucial differences set them apart.
1. Case Feeding Mechanism: The Core Distinction
The most significant difference lies in their case feeding systems.
-
Dillon 550B: Employs a case-activated feeding system. This means the press only advances to the next case once the previous case is fully seated in the shell plate. This ensures reliable feeding and prevents double-feeding, making it a great option for beginners and those prioritizing reliable operation. However, this can result in slightly slower reloading speeds.
-
Dillon 550C: Utilizes a power-activated feeding system. A small motor powers the case feed, leading to a significantly faster reloading speed. This increase in speed is noticeable and appealing to high-volume reloaders. The power-activated system is more complex, however, and may require slightly more maintenance.
2. Speed and Output: A Matter of Preference
The difference in case feeding directly impacts the speed of the presses:
-
Dillon 550B: Offers a reliable and consistent reloading process but at a moderate speed. Expect to produce approximately 800-1000 rounds per hour. This is perfectly adequate for most hobbyist reloaders.
-
Dillon 550C: Boasts a considerably higher reloading speed, producing upwards of 1500-2000 rounds per hour. This makes it ideal for high-volume shooters, competitive shooters, or those who frequently reload large quantities of ammunition.
3. Complexity and Maintenance: A Balancing Act
The increased speed of the 550C comes with some trade-offs:
-
Dillon 550B: Relatively simpler in design, making it easy to maintain and troubleshoot. Fewer moving parts translate to less potential for mechanical issues.
-
Dillon 550C: The integrated motor and more complex feeding mechanism mean there are more parts that can potentially require maintenance or repairs. While still reliable, it has a slightly higher potential for malfunctions compared to the 550B.
4. Cost: Considering Your Budget
The differences in features directly impact the price:
-
Dillon 550B: Generally less expensive than the 550C, making it an attractive option for those on a budget or new to reloading.
-
Dillon 550C: Commands a higher price due to the added complexity and increased speed. This increased cost is justified by the higher output and efficiency for high-volume reloaders.
Choosing the Right Press: A Decision Matrix
The table below summarizes the key differences to aid your decision-making process:
| Feature | Dillon 550B | Dillon 550C |
|---|---|---|
| Case Feeding | Case-activated | Power-activated |
| Speed | Moderate (800-1000 rounds/hour) | High (1500-2000 rounds/hour) |
| Complexity | Simple | More Complex |
| Maintenance | Low | Moderate |
| Cost | Lower | Higher |
| Ideal For | Beginners, moderate volume | High-volume reloaders |
Case Study: The Competitive Shooter
A competitive shooter needing to reload thousands of rounds weekly would benefit significantly from the increased speed and output of the Dillon 550C. The higher initial cost is quickly offset by the time saved and increased efficiency.
Case Study: The Beginner Reloader
For a beginner, the Dillon 550B offers a gentler learning curve and a more forgiving system. Its simpler design and reliable operation make it easier to master the basics of reloading without the complexities of the 550C's motor and power system.
Conclusion: Making the Right Choice
The choice between the Dillon 550B and 550C ultimately depends on your individual needs and reloading volume. The 550B is a solid choice for beginners and those who reload at a moderate pace, prioritizing reliability and ease of use. The 550C, with its significantly faster reloading speed, is better suited for high-volume reloaders who value efficiency and speed. Carefully consider your reloading goals and budget to select the press that best aligns with your requirements. Regardless of your choice, both Dillon presses are renowned for their quality and durability, ensuring years of reliable service.
