A Detailed Comparison Between Dillon 550b And 550c

It is true that Dillon has been the pioneer when it comes to manufacturing reloaders. When it comes to reloading presses their products are reliable as well as durable. 


Getting back to the discussion of Dillon 550B VS 550C, we must say that the Dillon 550B and 550C are two of the most popular options on the market. Below are some of the features that you can rely on:


The main difference between the two presses is that the 550C is a larger, more heavy-duty version of the 550b. If you plan on doing a lot of reloading or you’re looking for a press that can handle more demanding loads, the 550C is the way to go. 

However, the 550B is still a great press for most reloading applications. It’s smaller and lighter, making it easier to set up and use. 


The Dillon 550B is a single-stage reloading press that is popular for its versatility and durability. It can be used for a variety of different calibers, and it is built to last. 

The 550C is a two-stage reloading press that is faster and easier to use than the 550B. It is best for experienced reloaders who are looking for a press that can handle high volumes of ammunition. That is correct, as it is fast and easy to press. This is why it can control ammo and you can work with a variety of calibers.


The 550b is a single-stage press, while the 550C is a progressive and two-stage press. This means that the 550C can reload ammo much faster than the 550b. 

So, what this translates into is that if you are looking for a machine to reload ammo for your own personal use, then the 550B is probably the better choice. It’s less expensive and it’s easier to use. 

However, if you’re looking for a machine to reload ammo for competition or commercial use, then the 550C is the better choice. It’s faster and can produce more ammo in a shorter period of time.

In short, it really depends on your needs. If you’re just getting started in reloading, then the Dillon 550b is a great choice. If you’re looking for a machine to produce large amounts of ammo quickly, then the Dillon 550c is the better choice.


Both the presses are ergonomically designed for your good. Nevertheless, the 550B is the bigger of the two presses and can handle larger calibers. Yes, you may need a larger area to house it.

On the other hand, the 550C is more compact, making it a good choice if space is limited. That said, we still would say that the two presses are easy to set up because you get the name of Dillon with them. Dillion knows how to make its loyal patrons feel safe and easy. 

Performance Price

In the end, it comes down to your needs and budget. If you’re looking for a powerful reloading press, the Dillon 550C is a great choice. To tell you the truth, the 550 B is less expensive than the 550c. 

What this suggests is if you have a budget to stick to, then you must consider the 550B as an option too. Nonetheless, both are durable and can handle more rounds per hour.
