What is the Best Grain for 5.56 NATO?

The 5.56x45mm NATO cartridge has been a staple of military and civilian shooters alike for decades. With its impressive range and accuracy, it’s no wonder why so many choose to shoot it. But with so many grain options available, deciding which one is best can be a daunting task. In this article, we’ll dive into the world of 5.56 NATO grains and explore which one reigns supreme.

The Standard: 55-Grain FMJ

When it comes to 5.56 NATO, 55-grain full metal jacket (FMJ) is the standard. This grain size was originally developed for the US military and has since become the most widely used grain size for civilian shooters as well. The 55-grain FMJ offers a good balance between accuracy and penetration, making it a great all-around choice for target shooting and hunting.

The Alternative: 62-Grain FMJ

For those looking for a bit more stopping power, 62-grain FMJ is a popular choice. This grain size is a bit heavier than the standard 55-grain, which translates to more kinetic energy and penetration. This makes it a great option for hunting larger game and those who need a bit more oomph behind their shots.

The Performance: M855A1 vs M855

One of the most debated topics in the world of 5.56 NATO is the M855A1 vs M855. Both grains are designed for similar purposes, but they differ in their construction and performance. M855 is a traditional 62-grain FMJ with a copper jacket, while M855A1 is a newer 62-grain FMJ with a lead core. The M855A1 offers improved penetration and a more consistent performance, while the M855 is known for its accuracy and reliable feeding.

The Specialty: Green Tip and Steel Penetrators

For those who need a bit more… um, penetration, there are specialty grains like green tip and steel penetrators. These grains are designed to penetrate armor and heavy cover, making them perfect for military and law enforcement applications. However, these grains are not suitable for civilian use and are typically only available to authorized agencies.

The Controversy: Hollow Points and Expanding Bullets

One of the most debated topics in the world of 5.56 NATO is the use of hollow points and expanding bullets. These grains are designed to expand upon impact, creating a larger wound channel and more effective penetration. However, some argue that these grains are not suitable for combat or hunting, as they can cause excessive pain and suffering. Others argue that they are a necessary tool for self-defense and hunting larger game.

The Verdict: What’s the Best Grain for 5.56 NATO?

So, what’s the best grain for 5.56 NATO? The answer ultimately depends on your specific needs and preferences. If you’re a target shooter or hunter looking for a reliable and accurate grain, the 55-grain FMJ is a great choice. If you need a bit more stopping power, 62-grain FMJ is a good option. And if you’re a military or law enforcement operator, green tip and steel penetrators may be the way to go.
