Reloading die helps to ensure that you are reloading the grass in a precise and reliable manner so that the reloading process occurs in a more precise and reliable way.

While this sounds great to the avid marksman, the truth is that a new person to the hunting or target shooting world may be a little intimidated at this point. They may have minimal knowledge of what the reloading die does, and how choosing the right brand or model can actually make you much more effective with your weapon.

If you are a person who spends a lot of time out on the range or hunting as I do, you are probably well aware that creating your own ammunition and being able to do so accurately and efficiently is a necessity. Hopefully this review will be able to give you the kind of information you need to get the perfect die set kit for yourself. There’s no doubt that you want the very best reloading dies for accuracy, and this review will hopefully give you the information you need.

How to Make the Right Choice?

Before telling you about the best reloading dies for accuracy that you can purchase, I wanted to tell you about what I considered to be the most important features of a reloading die set. So here are five quick ones for you:

  • What kind of die set do you need?
    This depends completely on the kind of case, as you may need a three die set option if you’re using a straight case.
  • Do you need a special crimping die to properly seat the bullet?
    This may be present in the set you are purchasing, so be aware of the need for this die if the caliber weapon you are using requires it.
  • Do you need a specialty die?
    There are different specialty dies out there, including the bump die which aids in chambering the bullet, the hand die, which is operated by hand, among others.
  • What kind of material is the die made of?
    Most standardize that you will purchase are made of a hardened steel, but that is not always the case. There are carbide dies, which contain a ring of tungsten carbide as one example. Knowing this is important, because this will determine if you need lubricants or not.
  • Will you need lubricants?
    While this is usually determined by the kind of material create the die, you may find that there are other reasons why a lubricant would be necessary. If you don’t want the extra expense, you may want to look at using a type of die that does not require it

Most Frequently Asked Questions

Why you need a reloading dies?

Reloading dies allow you to be able to create your own ammunition and ensure that it properly loads into the weapon without losing accuracy or efficiency. This will not only provide you with a big cost savings but gives you a fun way to be more in control when out hunting or taking target practice. It also ensures that you get the same quality ground each time, because of your ability to control the manufacturing process.

What Do Reloading Dies Do?

Reloading dies are typically sold in sets of either two or three guys. The three die set is normally used for straight cases, while the two die set is used for bottlenecked cases. The first die in the set is used for the sizing and decapping operation. The middle die, when you were talking about a three die set, expands the mouth of the straight case. In a two die set this would not be present. The last die is used set the bullet in the seat.

How do reloading dies work?

The reloading die is really a simple process. After cleaning the brass cartridges, which is always a good idea to do, the die set allows you to resize the cartridge case to fit the chamber of your gun as needed. The pressure on the bullet caused by the weapon because the brass to shrink, meaning that you need to do a resizing he able to get the brass back to its original size.

This is where each piece of the die kit comes into play. There will be a part that will specifically work with the neck, to include the case mouth. You are able to reopen the case, properly reshape the case, and prepare it for filling with ammunition all on your own.

Some die kits come with a tool that allows you to seek the bullet so that the case mouth is at its proper depth. Others come with a crimping die that evens and removes the bell. All of these play a part in ensuring that you get the round you need for your weapon and this is why there are specific ammunition die kits for different round sizes.

Carbide vs Steel Reloading Dies – What’s the difference?

The primary difference between these two is related to the need for lubricant. Carbide are a little bit more durable in the sense that they last longer than your standard steel reloading dies. Part of the reason that they had become so popular, beyond longevity, is the fact that a lubricant is not required. This is a saving to consumers.

The steel options are still outstanding in terms of quality. Many manufacturers provide lifetime warranties on their steel die sets because of the quality in terms of design and development. However, lubricants are needed for use, adding cost.

How to tell if you have steel or carbide dies?

The truth is that there is really not a significant difference between the two. Both you steel on the outside of the body, but in the carbide option, there is a carbide insert that you can visibly see. This is not present in the steel die options, making it easy to be able to detect. You will easily see this as a ring at the mouth of the die. It is slightly darker than the rest of the sleeve.

What are the basic types of Reloading Dies?

To understand the differences between the types of reloading dies there are really two main categories to begin with. The first starts with whether you are talking about a two, three, four, or Collett die set. The names tell you a lot about each of the sets, as the two, three, or four pieces come with a specific number of pieces necessary for you to be able to develop and properly load the round you need for your weapon.

It should be noted that the more I pieces that are necessary, the greater the precision you were going to have. However, these sets are a little more expensive and require greater time on your part to develop rounds and properly seat them within the weapon.

The three guys set, as an example, allows for full-length sizing and includes the full-length sizing die, a bullet seating die, a factory crimp die, plus additional accessories. However, these three pieces make up the base of the kit. The two-piece die set does not come with a factory crimp die.

The Collett die set is used to create the absolute best accuracy in terms of the round that you are creating to go in the gun chamber. In fact, no other type of die set is able to create a more accurate round then this particular set.

Your next type of reloading die category to look at is whether you are talking about carbide or steel. When using a steel die set, it requires that a lubricant be used, otherwise, damage may occur to the die set. This is not true of the carbide set, which provides a natural lubricant of its own.

Who makes the best reloading dies?

The two brands that stand out the most are Lee and RCBS. They have become the standard with many who create their own rounds, but it is not limited to these particular brands. As I have shown you in this review, Hornady and Redding also produce spectacular die kits that are fantastic. In fact, the Redding option I provided for the 308 Reloading Dies Set may be the best ammunition reloading kit of all.

These are the kind of names that you can count on to provide you with quality die sets no matter which caliber round you are talking about. However, don’t get locked into the brand name. Look around to see what consumers are saying about each particular kit, which is one of the things that I did in producing this review. I wanted to give you the very best, and that was not always the top one or two brands that consumers are used to.
