What is 5.56 Brass For Reloading? 🤔

It is a type of brass cartridge used in reloading rifle ammunition. It is most commonly used in 5.56 NATO and .223 Remington cartridges due to its strength and reliability.

Best 5.56 Brass For Reloading

Is 556 And 223 The Same? 🤨

No, 5.56 and .223 are not the same.

🧷 While both use a .224-diameter bullet, they differ in terms of pressure and brass composition.

🧷 5.56 rounds typically generate higher pressures than .223 rounds and are loaded into thicker brass casings that can withstand the increased pressure when fired.

🧷 5.56 is designed to be fired out of longer rifle barrels which release more energy than a shorter handgun or carbine barrels used for firing 223 calibre ammunition.

How To Choose 🧐

💡 Firstly, the brass should be free of flaws and imperfections.

  • 🔎 Look for brass that is properly alloyed and annealed for reloading accuracy and consistency.
  • 🔎 The brass should be sized correctly to ensure proper fit in your firearm chamber.
  • 🔎 You’ll want to look for brass that has been properly de-burred to avoid any potential issues when loading into a magazine or chamber.

💡 Another is the headstamp.

  • 🔎 This marking will indicate the brand of brass as well as the type of metal used in its construction so it’s important to know what you’re looking for before making a purchase.
  • 🔎 Make sure that your chosen 5.56 brass is compatible with your firearm’s chamber size prior to purchasing; some cartridges may require special sizing or trim prior to use.

💡 Lastly, while it’s not essential, reloaders may find it beneficial to buy 5.56 Brass already prepped in order to save time during the process itself.

  • 🔎 Prepped brass will often come already resized and de-burred which will reduce setup time immensely when loading up rounds for shooting or competition purposes.

Primer Crips 😎

Primer crimps are a process associated with reloading 5.56 brass casings.

✅ This type of casing requires a special, more rounded or “V” shaped crimp around the base of the primer pocket to ensure that the primer is not pushed out of the casing upon firing.

✅ Primer crimping helps to keep consistent and accurate pressure on the primer, which then helps create more uniform rounds when shooting.

🌐 The most common type of primer crimp for 5.56 brass casings is a roll crimp.

  • ➰ This involves rolling the edge of the pocket over at an angle in order to provide sufficient force for keeping the primer firmly seated in place but also allows for easier removal and reinsertion of a new primer should one need to be replaced.
  • ➰ The angle of this crimp is typically between 10-15 degrees, with 12-13 degrees being optimal for most applications.
  • ➰ For some cases, an additional taper crimp may be used towards the end of the pocket in order to further secure the primer within its seat and further improve accuracy.

🌐 All in all, using primers with an appropriate and properly applied crimp helps to ensure that rounds fired from 5.56 brass casings are as accurate as possible, helping you hit your targets consistently time after time!

Reloading 5.56 Brass 🕵️‍♂️

✅ To start, make sure you are working with quality 5.56 brass that has been previously fired from an M4 or similar weapon system.

❌ Do not attempt to use another sort of brass, such as .223 Remington or .308 Winchester; only 5.56 NATO should be used when reloading for this cartridge!

⭕ Once you have gathered all of your supplies, including primers, powder, and bullets, begin by depriving your brass using a deprimer tool; this will help prevent any potential misfires due to improper seating of the primer into the case head.

🚩 Resize your cases with a resizing die before trimming down any cases that have exceeded their maximum length limitations (2.26”).

🚩 After this step is completed, clean off any excess lubricant inside each case with a cloth or tumbler media before swaging primer pockets and flash holes with special tools to ensure the proper functioning of the round in your weapon system.

🚩 Add powder and seat primers into each case before finally adding a bullet to each one individually (with enough force to crush the bearing surface against the mouth of each case).

🚩 Once finished, crimp each round slightly so that it stays securely in place when fired from your rifle; this will help ensure consistent accuracy on the range or in the competition!

🚩 The last step is simply testing out your newly reloaded 5.56 brass rounds on an outdoor range or in competition – always use caution when firing freshly loaded rounds!

FAQ 🤠

Can I reload the factory brass?

YES, you can reload factory brass.

🔰 Most 5.56 brass is made with high-quality material and built to last numerous reloading cycles. 🔰 When reloading factory brass, it is important to inspect each individual case for any signs of wear or damage, as this could lead to dangerous issues during the reloading process.

How to prepare bulk brass 5.56mm?

Preparing bulk brass requires attention to detail and a few simple steps to ensure the reloading process goes smoothly.

💥 To get started, measure out the cases using a calliper and use a cleaning brush or tumbler to remove all dirt, dust, grime and other debris from the brass before loading it into your press.

This is important for ensuring consistent results; any dirt or dust on the cases can create problems when reloading because it will contaminate powder, primers, bullets or other components of your ammunition.

💥Next, use a lube pad or lube stick to apply lubrication on each case so that it doesn’t bind during the reloading process; this will also help keep any dust or dirt away during loading.

💥 Once you have applied the lubricant, you should resize each case in your press as necessary to ensure consistency across all cases; this will ensure that they are properly fitted for your rifle’s chamber size and that they can be chambered easily after being loaded.

💥 Finally, you should inspect each piece of brass before loading it into your press to make sure there aren’t any significant defects such as dents, cracks or splits which could cause problems during reloading or when shooting later on.

If you find any defects in any of the brass pieces then these should be removed as they could affect accuracy when firing ammunition containing them later down the line.

We believe this video can be helpful for you 📺

Do you have to resize the brass when you reload?

Yes, you typically need to resize the brass when you reload.

🔰 Resizing, or neck sizing is the process of pushing and reforming the brass case back down to its original size so it can be used again. This ensures that your 5.56 brass cartridge fits correctly in the chamber and provides proper tightness for reliable firing and extraction.

Can I use 5.56 brass to reload 223?
Technically, you can use 5.56 brass to reload 223.

❌ However, it’s not the best idea. The 5.56 brass is thicker and has a slightly larger diameter than 223 brass. This means that it will require more pressure to resize and may not fit as snugly in the chamber.

❌ Additionally, 5.56 brass is typically dirtier than 223 brass since it’s fired in military weapons which tend to be less well-maintained than civilian firearms. For these reasons, it’s generally advisable to stick with using 223 brass for reloading your 223 rounds.

How can you extend the life of 5.56 brass?
Properly annealing 5.56 brass will help to extend its lifespan.
What is 5.56 brass used for?
They can be used for a variety of purposes, such as reloading ammunition or crafts. 5.56 brass is also popular among gun enthusiasts and shooters because it is relatively easy to obtain and relatively inexpensive compared to other types of brass.
How do I clean 5.56 brass?
They can be cleaned in several ways, but the most popular method is to use a tumbler. Simply add your dirty brass and media to the tumbler, turn it on, and let it run for a few hours. When it’s finished, your brass will be clean and ready for reloading.

Conclusion 🤩

Reloading 5.56 brass can be a great way to save money while shooting, and it’s also a fun hobby for many people. In this article, we’ve looked at some of the best 5.56 brass for reloading on the market today.

I have experience reloading shotshells but not brass casings. As a former trap shooter, I recall that there was a limit to the number of times a shotshell could be reloaded before the plastic case separated from the brass or the end no longer crimped properly. However, I am not sure if there is a similar limit for brass casings. I am curious to know how many times brass casings can be reloaded.

Reloading your 5.56 brass is an economical and efficient way to keep your ammo supply high. Depending on the quality of the brass, they can often be reloaded several times, providing you with reliable ammunition for countless shooting trips.
Usually, it can last anywhere from 5 to 10 reloads with proper care.

The number of times that brass casings can be reloaded varies and is influenced by several factors such as cartridge type, the quality of brass, and the care taken during the sizing process. In my personal experience, I have reloaded some 556 brass casings up to 12 times, after which I discard them in a designated bin for casings that have reached their limit. The decision to discard casings is usually made when the primer pockets become too loose.

The number of times brass casings can be reloaded largely depends on the caliber of the cartridge. However, it’s important to note that all brass casings eventually become work-hardened. To mitigate this issue, annealing can be done to prolong the casing’s lifespan. Additionally, it’s advisable to only size the casings enough to fit the chamber and ensure that they drop smoothly without any obstructions.

Thank you for all your replies and comments. I understood. Just to check – what is the lifespan of 556 brass?

The lifespan of brass depends on how it is cared for, stored, and/or used.

🟨 Generally speaking, if properly stored away from moisture and other contaminants, 5.56 Brass For Reloading can last indefinitely.

🟥 However, when exposed to high temperatures or extreme pressures – such as those generated by firing rounds – the lifespan can be significantly reduced.

🔔 Proper cleaning and lubrication of your reloaded brass after each use will help maximize its life span. Additionally, an inspection of the casing walls both pre-and post-firing is a must to ensure quality control standards are met with each round you fire!

Hello there! I have a considerable amount of M855 ammunition, and I am planning to start reloading 5.56 soon. Currently, I am only reloading 9mm until I become more comfortable with the process. However, I have noticed that some of the M855 brass casings have small dents on the side, even though they are unfired. I am aware that such dents can impact the internal pressure, so I am wondering if it’s best to discard them altogether. Any insights you can provide would be much appreciated. Thank you!

Dented brass, while not ideal for reloading, may still be used.

🟦 However, it is important to note that the dents can cause irregularities in the overall shape and size of the cartridge, making it difficult to fit into your firearm.

🟦 Additionally, these irregularities can cause pressure fluctuations during firing which can lead to excessive wear on the firearm.

Small dents on M855 brass casings are generally not a cause for concern. However, since military specification ammunition has crimped primers, you will need to swage the primer pockets before reloading.

Minor dents in the body of brass casings are typically not an issue, as long as they don’t impede the chambering or unchambering of the cartridge. Any minor dents can usually be resolved by using a full-length resizing die. Additionally, fresh dents will likely be installed by the deflector during the extraction and ejection of the casing.
