The Five Best 5.56 Reloading Dies [Reviewed] – Top Models

The Five Best 5.56 Reloading Dies [Reviewed] – Top Models

Many professional and amateur hunters consider reloading a fun and rewarding hobby. The 5.56mm is an arguably the most common round to reload, because the AR 15 rifle is very popular in U.S. When reloading, it is very important that you select the right set of dies for your rifle, because semi-auto rifles have different technical specifications than bolt-action ones.

You also need a set of sturdy dies, because you don’t want anything that will reloading less than 1,000 rounds at a time is simply not worth the time and effort. Fortunately, you can use 5.56mm reloading dies for .223 and vice versa. Although the two rounds have different pressure loadings, dies themselves are interchangeable.

The best dies come from American companies, and we have the top five 5.56 reloading dies for 2019 in the table below.

1. Hornady 546228 DIESET 2 223 REM Remington Custom Grade Reloading DIE Set (Series I Two-Die Set) (.224)

 Hornady 546228 DIESET 2 223 REM Remington Custom Grade Reloading DIE Set Many hunters are looking to keep things nice and simple, but they still want a quality set of dies. Well, their expectations will be surpassed by this set from Hornady – one of the world’s best known ammunition manufacturers.

The company produces a vast range of ammo, including custom match ammunition, without making even the slightest compromise with Hornady’s high quality standards. This particular die set is simple to use and it is designed for mass reloading.

These dies are for the type of guy who shoots a semi-automatic rifle and likes to press out a thousand or so rounds at a time. They are affordable, easy to use and, most importantly, they do the job!

For all their affordability and simplicity, these dies are far from cheap. This is why Hornady offers a lifetime warranty. They guarantee that their dies will never break or even wear from reloading 5.56mm and .223 ammunition.

These plain dies feature Hornady’s Zip spindle, which is somewhat new to the Hornady dies. Yet, it protects your hand while you are trying to tighten the spindle lock. But that’s not all, because it also keeps the spindle from slipping, which greatly facilitates spindle adjustment. Because of their simplicity and longevity, these plain dies are our top choice for 2019.


  • Simple to use
  • Lifetime warranty
  • Top quality manufacturing
  • Feature Hornady’s Zip spindle



  • The seating die took some time to set properly
  • Relatively pricey

2. RCBS Small Base (SB) Die Set .223/5.56

RCBS Small Base (SB) Die Set .223/5.56Although RCBS doesn’t have Hornady’s ammunition manufacturing claim to fame, they do have a lot to offer when it comes to reloading supplies, because they have been making them for six long decades, which means they know very well what they are doing.

The RCBS kit we have chosen to review here for the 5.56 and .223 are specifically designed for AR shooters. This makes sense, considering the fact that the AR rifle probably eats more .223 and 5.56 ammunition than any other firearm ever made in the world. The RCBS dies are designed for the progressive reloader, whose ultimate goal it is to pump out a large amount of ammunition in a short period of time.

This particular set of dies offers its user a full length, small base sizing die and a taper crimp seating die. The manufacturer guarantees that it sizes the brass consistently, so as to ensure chambering performance and unrivalled accuracy. The taper crimp seating die is designed to give you a little leeway in a safe manner.

It is also worth mentioning here that this die set is also quite affordable. At a very reasonable price one can get an astonishingly sturdy set of dies, well complemented by a very long warranty. Although they are not as simple to use as Hornady’s, these dies are made to be long lasting and tough, and can be used thousands and thousands of times. Therefore they have earned the number two spot on our list.


  • Very reliable;
  • Very long warranty;
  • High quality manufacturing;
  • Ensure outstanding chambering performance and accuracy;
  • Excellent customer care;



  • This set can sometimes resize the brass out of spec and cause the bolt to lock forward after every shot.

3. Lyman 223 Rem Carbide Deluxe Rifle 3 Die Set (5.56-mm)

Lyman 223 Rem Carbide Deluxe Rifle 3 Die Set (5.56-mm)The third set of dies on our list is what a shooter needs when they can afford to invest in their brass. Using standard Federal brass or Lake City is nice and cheap, but using nickel-plated, weather-resistant brass is a completely different experience. If you want to preserve this pricier brass of yours as long as possible, then Lyman’s dies are the right choice for you, as they prevent excessive sizing and greatly expand case life.

This set is certainly not the cheapest one on the market, but it is a reasonable investment for the consistent reloader. Without any doubt, these are among the best 5.56 reloading dies money can buy.

More often than not, when it comes to reloading 5.56 rounds, you only need 2 dies. But there is a huge difference between “need” and “nice to have. So the third die in the Lyman Deluxe rifle set is certainly not a necessity, but it is very nice to have. The product’s outstanding quality lends itself to the fact that Lyman is a well-known company that manufactures pretty much everything related to reloading.

This deluxe rifle set suits any .223 and 5.56 rifle, and it is the choice of shooters who are looking to maximize their case life. This set of three includes some standard dies with nice extra features. The first is the full length resizing die that is equipped with a decapping stem. Next you there is neck expanding button, as well as the bullet seating die.

You also get a third die, which is basically a neck sizing die with a carbide expander. This extra die enables the reloader to extend case life by reducing the amount of stretching caused by excessive sizing. These die sets are just perfect for loading jacketed bullets in bottlenecked rifle cases. Our number three pick is arguably the best choice for loading 223 Remington (5.56mm) cartridges.


  • Super hard and slick carbide expander;
  • Extends case life
  • High quality manufacturing;
  • Outstanding chambering performance;
  • Good customer care;



  • The guide rods can bend and jam in the shell

Lee Precision Reloading 223 Remington Ultimate Rifle Die SetThe Lee Precision Ultimate die set comprises of four different pieces. The full length sizer is designed predominantly for semi-automatic rifles. Although these rounds work with other rifles as well, they are most efficient with semi-auto designs like the AR 15. This die set also includes a collet neck sizer that is designed for bolt action and single shot rifles.

Also, the bullet-seating die provides accurate placement of the projectiles in the case making it easier to crimp. Finally, the crimp die is used to swoop in and keep the bullet in place.

Lee Precision is the best choice of shooters who would like to learn to reload. The company produces a wide range of different reloading presses, including one of the best single stage presses on the market. Most reloaders pick a certain caliber to hone their skills and it is often either 5.56 or 9mm. To all 5.56 shooters, Lee Precision offers their Ultimate 5.56 die set. This set consists of everything you could possibly need to begin reloading 5.56 and .223 rounds.

Dillon Three-Die Rifle Die Set also includes a sizing and depriming die, a bullet seating die and a taper crimp die. The sizing/depriming die is a full-length one.

The manufacturer strongly recommends that a headspace case gage be used to correctly adjust the size die. The depriming assembly includes a carbide expander ball for effortless neck expansion. This expander ball is located in the middle of the depriming stem to take advantage of superior initial leverage for easier extraction.

In case of a stuck case, the design of the depriming assembly allows it to work as a stuck case remover. Dillon’s bullet seating die is designed to keep the bullet straight throughout the seating process. Once accurately adjusted, the only measurable runout will be that which is inherent in the bullet.

This manufacturer’s special taper crimp die is specially configured to center both the case neck and the case body, thus aligning the entire cartridge for a more uniform crimp. Dillon Rifle Dies are designed to meet the more rigid requirements for both accuracy and precision demanded by today’s shooters.


  • Sizing Die has a carbide insert for longer life span;
  • Increased scratch resistance
