Best Reloading DiesReloading your own bullets is a great way to save money on ammunition. It also gives you the ability to precisely adjust the load for improved accuracy and velocity. However, it requires investing in the proper equipment, including a quality set of reloading dies for each type of cartridge you plan on reloading.

The best reloading dies allow you to make sure your bullets are properly made for consistent feeding and ejecting, as well as precise shooting. On the other hand, a set of cheap reloading dies can easily result in bullets that could jam up your firearm or simply suffer from poor performance.

What Are Reloading Dies and How Are They Used?

Dies are one of the most important reloading tools, which serve a number of essential functions depending on the type. Each set normally includes three or four dies—each of which is designed for a different purpose, such as resizing, expanding or decapping the cartridge. The dies are designed to screw into the reloading press, providing a secure base for performing all of the required tasks.


The resizing die is the first die used, which allows you to return the cartridge back to its original industry standard size. After decapping the primer, cleaning the cartridge and repriming it, you’ll then move on to the expanding die. This die is used to expand the mouth of the cartridge to ensure that the bullet fits properly inside it.

After quickly checking to see that the bullet fits, the next step is to use a funnel to fill the cartridge with powder. From there, you can simply finish by using the bullet seating die to fit the bullet into the cartridge. However, some people prefer to first use an additional crimping die to slightly adjust the shape of the cartridge so that the bullet fits better. Crimping the cartridge generally produces a more accurate round, but it’s definitely not a necessity, which is good news for those of you looking to save time.

Each three or four die set is designed to fit a specific caliber of cartridge, meaning you’ll need to purchase one set for every type of ammunition you want to reload. However, there is one exception—the decapping die. This die is used to remove the spent primer either before or after resizing the cartridge. Most decapping dies are universal, meaning they will work on almost every type of cartridge.

It’s also possible to find sets where the resizing die can also be used for decapping, and even simple two die sets where the resizing die also widens the mouth of the cartridge, eliminating the need for a separate expanding die.

What to Look for in Reloading Dies?

When purchasing reloading dies, it’s always a good idea to invest in the best possible option. A high quality set of dies should last for years and years, so there’s no reason to be unnecessarily cheap with your purchase. The fact that they are so long-lasting means you can easily find thousands of used reloading dies for sale online. However, buying used dies generally isn’t recommended unless it’s your only option or you happen to be buying them from a close friend who you know took proper care of them.

The problem is that if the dies are slightly damaged in any way, it could result in you spending all your time and money making bullets that couldn’t hit the broad side of a barn. For this reason, it’s always a good idea to invest in a quality set of new dies from a well known, reputable manufacturer.

All dies are generally made from solid machined steel, so there’s not that much to separate most of the top brands. All dies should also theoretically be made from case-hardened steel, but this doesn’t always seem to be the case with some of the cheaper brands, many of which tend to use inferior quality steel.

Generally, you should expect to pay somewhere between $30 and $60 for a good set of cartridge-specific dies, plus another $10 to $20 for the decapping die. This means that you could easily end up spending several hundred dollars on dies alone if you plan on reloading several different calibers of ammo. Nonetheless, it will more than make up for itself in time due to all the money you’ll save by no longer having to buy bullets.

The Best Reloading Dies for Each Caliber


Trying to decide which reloading dies to buy is both a simple choice and a difficult one at the same time. The reason being that—if you’re truly looking for the best reloading dies—there are really only a handful of choices for each caliber. Generally, the choice will come down to one of three top brands:

  • Lee
  • Hornady
  • RCBS

Each of these brands produces a range of different reloading dies in virtually every caliber imaginable, leaving you several outstanding options. While there is very little to separate the dies from any of these brands, after a large amount of research and testing, we’ve chosen our top pick for some of the most popular calibers.
