How to Adjust Reloading Dies?  

Adjustment of reloading dies is one of the main tasks of reloading. A faulty adjustment can totally mess up your reloading. Therefore, for precise reloading, the importance of perfect adjustment is inevitable. 

The sizing die & the seating die are the two dies that you need to adjust. Below are the ways to adjust these dies. 

Sizing Die Adjustment: 

  • Start with screwing the die into your press until the die touches the shell holder. 
  • When the die touches the shell holder, screw the lock ring down so that it gets set. 
  • Now just screw the set screw and your adjustment is done. 

Seating Die Adjustment: 

  • Start with a brass placed on your shell holder. 
  • Now take the seating die and start screwing in until it touches the brass. This time make sure you are not touching the shell holder but the brass. 
  • Unscrew a quarter turn. Doing so will prevent the case from crimping.
  • Raise the seat stem to its highest position.  
  • Set the lock ring. 

Your die will be adjusted. However, you do need to adjust your seating depth and here’s how you do that. 

  • Place a loaded bullet into the shell holder and bring that up. 
  • Bring down the seating stem until it touches the bullet, 
  • Lock that. Your seating depth is adjusted. 

9mm Reloading Dies vs 5.56 Reloading Dies

When it comes to differences between a pistol reloading die and a rifle reloading die, few things are distinctive. When you are reading 5.56, you have a choice between a neck die or a full-length die.

Another difference can be found in the crimping system. Crimping is a pistol exclusive feature that most of the 9mm reloading dies feature.

A pistol die can be either a taper or a profile crimping die. In the case of crimping rifle bullets, this is rather rare. Because of this, most of the dies don’t come with such features. 

How To Choose The Best 5.56 Reloading Dies – Buying Guide 

Reloading dies may seem simple, but you can easily buy a wrong one too. Therefore, it is always advisable to consider a few of the factors, so that you don’t make a mistake. Below are some of the aspects that you should not ignore while getting a set of reloading dies. 

The shape of the Case:

If you are going to reload straight cases, going for a 3-piece die set is recommended. However, if your cases have a bottleneck shape, go for a 2-die set. 

Reloading Frequency: 

How frequently do you reload? If you are a casual reloader, you may cut some additional tools as you may not need them. For instance, a hand die which is used to mod the neck cartridges. However, for a seasoned reloader, those are very important. 

Specific Design: 

Dies are specifically designed to reload different types of calibers. Some dies are made for 9mm bullets whereas some others are only made to reload 5.56 ammo. As you are looking for a 5.56 reloading die, make sure you check properly. Don’t lose money by buying the wrong die. 


When it comes to being reliable and ensuring quality, considering brands is highly suggested. Brands like Hornady, Lyman, RCBS, and Lee are manufacturing dies for a really long period. Each one of them are known for their outstanding performance, quality, and reliability. 

Type of Press: 

Last but not least, check your press type as well. Presses do come in different types such as single-stage, turret press, or progressive press. Each press has its own specification, and thus needs specified dies. Therefore, the importance of understanding which type you use and what dies you want is fundamental.
