Important To Know😎


This ammunition traces its roots back to the post-World War II era. The need for a high-velocity, lightweight rifle cartridge for the military led to its development. The Armalite Corporation, a small arms manufacturer, first introduced the 5.56 Ammo in the late 1950s, in response to the NATO requirements for a standardized ammo. The ammunition was first employed in the M16 rifle which became a standard issue for the U.S. military during the Vietnam War.


These NATO rounds are known for their impressive specs. They have a standard weight of 3.95 grams (62 grains) and offer a high velocity ranging from 600 to 920 meters per second (2,000 to 3,020 feet per second) depending upon the type of bullet and barrel length. The bullets are typically copper jacketed, have lead core and have a diameter of .224 inches.


This ammunition is widely recognized and praised for its exceptional performance in both semi-automatic and automatic rifles. With its carefully engineered design, this ammunition showcases minimal recoil, allowing for rapid and precise firing even in intense combat scenarios. Notably, its high velocity contributes to a flatter trajectory, ensuring remarkable accuracy even over extended ranges.

🟡Target Shooting

Target shooters often favour this ammo because of its accuracy and consistency. The ammunition’s high-velocity results in a flat trajectory, making it an excellent choice for target shooting at varying ranges.

🟡 Small Game Hunting

It is also popular among small game hunters. Its high velocity and lightweight allow for rapid, accurate shots, making it ideal for hunting small, fast-moving animals.

🟡 Law Enforcement

Law enforcement agencies commonly use this ammo in their service rifles due to its reliability and accuracy. It allows officers to respond quickly and effectively in high-pressure situations, ensuring public safety.

🟡 Competitive Shooting

In the realm of competitive shooting, this ammo is a popular choice. Its accuracy, coupled with its manageable recoil, allows competitors to achieve consistent, precise shots, which is crucial in competitive scenarios.


FMJ is the most common type. It features a soft lead core surrounded by a shell of harder metal, usually copper. This design improves the bullet’s durability while preventing lead from accumulating in the barrel. It’s often used for military training, target shooting and plinking.

Soft Point ammo is designed to expand upon impact, increasing its effectiveness for hunting and self-defence. The exposed lead at the tip of the bullet allows for more energy transfer to the target, resulting in a larger wound channel.

Hollow Point ammo features a small hollowed-out area in the tip of the bullet, causing it to expand upon impact, maximizing tissue damage and stopping power. It’s commonly used by law enforcement and for self-defence, but it can also be used for hunting small games due to its terminal performance.

OTM ammo is engineered for precision. These bullets have a small opening at the tip but are not designed to expand like a hollow point. Instead, they are manufactured to exact tolerances to ensure consistent performance, making them a favourite among competitive shooters.

Reloading 🔄

Reloading can provide a host of benefits, ranging from cost savings to the ability to fine-tune loads to maximize accuracy. It’s a process that, while requiring meticulous attention to detail, can yield rewarding results for shooting enthusiasts.

Advantages 🎯

Reloading ammunition allows for customization of loads, enabling shooters to optimize the performance of their firearms. It can offer substantial cost savings over buying factory ammunition, especially for high-volume shooters. By re-using brass, shooters reduce waste, making reloading a more environmentally friendly choice.

Necessary Equipment 🔧

A basic reloading kit typically consists of a reloading press, reloading dies for the specific calibre (in this case 5.56), a scale for measuring powder, a powder dispenser, callipers for measuring overall length, a primer tool, and a case trimmer. Other helpful tools include a case cleaner, a case lubricant, and a bullet puller.

Step-by-Step Guide 📒

  1. Case Inspection and Cleaning – Inspect the used brass for any visible defects. Clean the brass using a case tumbler or ultrasonic cleaner to remove any dirt or residues.
  2. Resizing and Decapping – Use your resizing die on the reloading press to reshape the brass back to its original dimensions. This process also removes the spent primer.
  3. Primer Pocket Cleaning and Swaging – Clean the primer pocket to remove any remaining residues. If needed, swage the primer pocket to remove any crimps left from previous primers.
  4. Trimming and Chamfering – Trim the case to the correct length using a case trimmer. Chamfer the case mouth for easier bullet seating.
  5. Priming – Using a priming tool, insert a new primer into the base of the case.
  6. Powder Charging – Measure and dispense the correct amount of gunpowder into the case using a powder measure and scale.
  7. Bullet Seating – Place a new bullet on top of the case and use your seating die to press it into place.
  8. Crimping – If desired, crimp the case mouth around the bullet using a crimping die.

Cleaning 🧽

Cleaning the brass is one of the essential steps in the reloading process. A case tumbler with either walnut shell or corn cob media is a common method of cleaning brass. Ultrasonic cleaners or wet tumbling with stainless steel media are also effective methods that can provide greater cleaning, inside and out, including the primer pockets.

Safety Rules 🔒

Safety is paramount when reloading ammunition. Always wear safety glasses to protect your eyes from potential hazards. Make sure to handle gunpowder and primers in a well-ventilated area, away from open flames or sparks. Follow load data from trusted sources, and do not exceed recommended powder charges. Keep detailed records of your loads.

Storage Rules 📦

Store your reloaded ammunition in a cool, dry place, away from heat sources or moisture. Ammunition should be stored in labelled containers that list the calibre, bullet weight, type of powder, and powder charge. This can prevent confusion and ensure safe and reliable use of your reloads.

Are 5.56 Bullets More Accurate Than FMJ From An AR-15?

In comparing the accuracy of this ammo it’s important to clarify that 5.56 NATO refers to a specific calibre of ammunition, and FMJ is a type of bullet design, which can be used in many calibres, including 5.56.

The FMJ bullets are designed for durability and prevention of barrel lead accumulation, making them ideal for military training, target shooting, and plinking. However, the accuracy of a bullet depends not just on its design, but also on factors such as the barrel length of the firearm, the shooter’s skill, and environmental conditions.

For the AR-15, which is typically chambered in 5.56x45mm NATO, the type of  bullet used can indeed affect accuracy. For instance, FMJ bullets are reliable for general purposes, but open-tip match (OTM) bullets, specifically designed for precision, may provide superior accuracy, particularly at longer ranges. These bullets are manufactured with careful tolerances to ensure consistent performance, a key factor in achieving precise shots.

Is .223 ammo or 5.56 ammo Better?

They are very similar cartridges, but there are some key differences. The NATO ammo is a higher-pressure cartridge than the .223 Remington, which means that it can be loaded with more powder and produce a higher muzzle velocity. It is also slightly longer than the .223 Remington, which gives it a slightly longer case capacity.

In general, the 5.56x45mm NATO is considered to be a more powerful cartridge than the .223 Remington. However, the .223 Remington is still a very effective cartridge and is often used for varmint hunting and target shooting.

Here is a table summarizing the key differences:

Feature 223 Remington  5.56x45mm NATO

How Effective Is 5.56 Green Tip Against Steel?

When evaluating the effectiveness of our ammunition against steel, two popular choices often surface: the Full Metal Jacket (FMJ) and the “Green Tip” M855. The distinction between these two lies in their construction and resulting performance characteristics.

🔰 The FMJ is a traditional design, encasing the lead core of the bullet in a hard shell of copper or similar material, but leaving the base of the bullet exposed. This design is versatile and reliable for a wide range of applications, from military use to recreational shooting.

🔰 The Green Tip M855, on the other hand, is a type of FMJ ammunition specifically designed with a steel penetrator tip, painted green for identification, and a lead core. The steel penetrator enhances the ammunition’s ability to penetrate targets, and this is particularly evident when it comes to steel.

In a direct comparison, the Green Tip M855 exhibits superior performance against steel targets when compared to standard FMJ rounds. The steel penetrator tip allows the M855 to pierce through steel more effectively than FMJ bullets. However, it’s essential to note that the use of M855 rounds may cause increased wear and tear on steel targets due to their penetrating capabilities.

Therefore, while the 5.56 Green Tip M855 may offer improved performance in penetrating steel, it is crucial to consider target durability and the intended application before choosing between M855 and standard FMJ ammunition.

We can assure you that this video will certainly clarify the difference📺


In conclusion, the 5.56x45mm NATO ammunition is a versatile and highly efficient rifle cartridge that has proven its worth in various applications. Its impressive velocity, low recoil, and lightweight nature make it a trusted choice for military operations, law enforcement, home defence, and hunting. Whether it’s FMJ, Soft Point, Hollow Point, or OTM, each type offers unique advantages tailored to specific situations. From competitive shooting to target practice, its use is widespread, reflecting its reliability and high performance. It’s clear that this ammo stands as a testament to the blend of engineering and innovation in the realm of ammunition creation

Greetings. How available is 5.56 ammo for civilian purchase?

    2 months ago
    Reply to  Gail

    The availability of 5.56 mm ammo for civilian purchase varies depending on the location. In some areas, it may be readily available, while in others, it may be more difficult to find. This is due to a number of factors, including:

    💡 Current events: The availability of ammunition can be affected by current events, such as wars or political unrest. In times of high tension, there may be a greater demand for ammunition, which can lead to shortages.
    💡 Government regulations: Government regulations can also affect the availability of ammunition. For example, some countries have strict gun control laws that make it difficult to obtain ammunition.
    💡 Economic factors: The availability of ammunition can also be affected by economic factors, such as inflation or supply chain disruptions. These factors can make it more expensive or difficult to obtain ammunition.

    🏁 In the United States, the availability of 5.56 mm ammo for civilian purchase is generally good. However, there have been some shortages in recent years, due to a number of factors, including the COVID-19 pandemic and the 2020 presidential election.

    If you are looking to purchase 5.56 mm ammo, it is a good idea to shop around and compare prices. You may also want to consider buying in bulk, if possible. It is also important to be aware of the current laws and regulations in your area, as these can change frequently.

      And I liked the comparison with 223. The distinction in accuracy between 5.56 and .223 is of such marginal nature that approximately 90% of shooters, myself included, possess such proficient marksmanship that they wouldn’t discern any significant variance.

        A notable distinction exists between 5.56 NATO and .223 Rem ammunition in terms of primer hardness. Military surplus (mil-surp) ammunition typically features harder primers compared to civilian-grade rounds. This difference can lead to potential issues in firearms originally designed for .223 Rem. For instance, when I tested Federal M193 ammunition in my Savage 110 rifle, I encountered several instances of light primer strikes. Interestingly, this occurred exclusively with the mil-surp M193 rounds, as I fired a mix of these and civilian cartridges during that range session. Evidently, the firing pin spring in my Savage 110 proved insufficiently rigid to reliably ignite the harder primers found in mil-surp ammunition.

          Interesting! Especially about 7,62 nad 5.56. After utilizing the 7.62 for nearly half of my service and transitioning to the 5.56 for the remaining duration, the prominent distinction between the two lies in their stopping power. I’ve personally witnessed instances where the smaller round was halted by standard webbing.

            And range! Amidst the rugged terrain of Afghanistan, American soldiers armed with M4 rifles encountered a notable challenge: adversaries positioned more than 300 meters away seemed largely impervious to their gunfire. In contrast, the opposing forces, wielding .30-caliber AK-47s and even the formidable Mosin-Nagant battle rifles, could return fire without hindrance. These century-old .30-caliber battle rifles were conceived to deliver lethality at distances up to 2,000 meters. In contrast, the .223 caliber round was tailored for far humbler purposes, akin to being effective against much smaller targets.
