To help you match with the right 308 reloading dies, here are some features that you have to consider before choosing one. 

Quality

There are things you have to check if you want to know the quality of a .308 reloading dies you’re interested in. They should be effective at: 

  • Decapping 
  • Resizing and expanding the case mouth
  • Bullet seating
  • Crimping 

If the 308 reloading dies are very good at all these aspects, then it is a high-quality product that you should consider. 

The Frankford Arsenal Universal Bullet Seating Die is no doubt the best if we’re talking about quality. It has all the things you need for reloading in a set. 

Durability

You want your reloading dies to be tough so they can take any hard well-molded case and resize it easily. If the 308 reloading dies aren’t durable enough, they might 

Make sure that the decapping pin is also sturdy. It should be able to hold up for long hours without chipping, bending, breaking, or getting stuck. 

The Hornady Custom Grade New Dimension 2-Die Set has some of the best steel materials. Its design is also well-made and has the best durability and quality on this list. 

Number of Dies

Reloading dies come in different sets. Some can hold only one, and others hold two, three, up until four for a set. Reloading generally relies on the type of cases being used. Therefore, it is important that you know what particular sets would be useful for you. 

For reloading bottleneck cases, a 2 die set is best for the job. If you’re going to reload straight cases, a 3 die set is the optimal choice. If you’re looking for specialized dies, then go for 4 set dies which usually contain special dies like bump or hand die.  

This comes down to preference, and if you want one that accommodates all, the Frankford Arsenal Universal Bullet Seating Die is the obvious choice since it has all you need. 

Material

308 reloading dies are usually made with either carbide or steel. Both materials are suitable for certain guns. 

Carbide reloading dies for rifles are generally more expensive compared to their steel counterpart. Some people prefer using carbide reloading dies since it doesn’t require lube while reloading. However, that’s only the case for pistol rounds and not for rifles. 

For .308 rifle cartridges, you want to use lube even if you’re using carbide reloading dies. The main reason for this is to avoid hurting your shoulder and the cartridges don’t get stuck. Some like to use lube spray instead of lube which works the same as lube.  

Neck Resizing Dies

If you’re choosing a neck resizing die, you aren’t changing the size of the brass body. Instead, you will only be adjusting the neck of the shell. 

This is a great option if you want to reuse the shells multiple times. The accuracy also improves because the cartridges were formed by firing to fit your rifle perfectly. 

The RCBS Neck Resizing Die is a great choice for this. It also comes in cheap despite its great quality. 

Full-Resizing Dies

If you’re going for full-resizing dies, you want to create rounds that work in any rifle. However, there’s a downside to this process. It shortens the lifespan of the case you’re reloading. 

If you’re going for this, there are small base full-length sizing dies that are used with semi-automatic rifles. The smaller base gives extra compression to the brass. It ensures that the case is properly extracted from the firearm. 

The RCBS Full-Length Die Set is a great option if you’re going for full-resizing dies. 

Types of Reloading Dies

There are many types of reloading dies. You should know the different types to know what each reloading dies are used for especially if they come in a set.

  • Resizing/Depriming dies: These are used for resizing dies to adjust the size of the case. It has two subcategories that are mentioned above, full-resizing and neck resizing. 
  • Case Trimming Die: These help you to quickly and accurately trim the length of your brass
  • Powder-through expanding die: Generally used after the resizing and trimming dies. It expands the mouth of the case and drops the powder inside through the hollow expander.
  • Bullet seating die: The bullet seating die seats the bullet snugly into the loaded cartridge.
  • Factory crimp die: These crimp your rounds the same way as factory ammunition. It has a crimping “collar” inside which helps keep the bullet in place. It seals the round to protect the powder.  

How Many Times Can You Reload 308?

You should be able to reload 10 to 15 times using full-length reloading dies. Make sure you don’t bump the shoulders back too much. 

The more times you do reloading, the better you will get at it. Reloading is a fun hobby on its own. Most gun enthusiasts do reloading because they enjoy doing it by themselves.
