About 223 Ammo

The history of 223 ammunition, also known as 223 Remington or 5.56 ammo, dates back to the mid-1960s.

Developed by Remington Arms as a commercial cartridge for hunting and varmint shooting. Paired with AR-styled rifles, 223 ammunition quickly became popular thanks to its high accuracy, low recoil, and ability to shoot small game over long distances.

Although some AR-style rifles are chambered for .223 ammo, others are designed for 5.56 ammo. While these two calibers look almost identical on the outside, they do have subtle differences.

These differences include powder loads, bullet weights, and, most importantly, chamber pressures.

Over the years, 223 ammo quickly gained popularity in military and civilian circles and remains one of the most widely used cartridges worldwide.

The caliber's usage range from military combat, hunting, and target shooting.

Regardless of your preferred terminology, 223 ammunition has remained massively popular over the years and is available in the lineup of every significant ammunition manufacturer worldwide.

223 Ammo FAQ

QUESTION: What is 223 Ammo?

ANSWER: 223 Remington is a rifle cartridge designed by Remington Arms as a primary round for a project to fulfill the U.S. military's search for a new rifle and round.

The round is essentially a 22-caliber projectile with a larger powder cartridge to provide more power for long-range purposes.

QUESTION: What is 556 Ammo?

ANSWER: Officially called 5.56 x 45mm NATO, 5.56 is the designation for the military version of 223 ammunition. Based on the millimeter measurement for the round, 5.56 is the general term for the round in common conversation. It's one of the primary rifle rounds utilized by NATO countries.

QUESTION: Are .223 and 556 Ammo the same?

ANSWER: While the two cartridges are modifications of the same platform, they aren't always interchangeable. While 223 ammunition is compatible with a 5.56 rifle in most cases, a 5.56 can significantly damage a barrel and chamber when fired from a rifle only designed to shoot 223.

QUESTION: What is the Difference Between 223 and 5.56 Ammo?

ANSWER: In terms of the measurement of the round itself, the cartridges are virtually identical. The diameter of the bullet is the same, but the casings have slight differences.

Additionally, the powder load is bigger for the 5.56. This creates differences in chamber pressure when fired.

QUESTION: Which Ammo is Better: 223 or 556?

ANSWER: There is no clear better choice between the two rounds as an objective standard. However, there can be a better option for your particular situation.

The two rounds each have their own pros and cons, and each will have potential benefits depending on your rifle and your specific usage.

QUESTION: What is a 223 good for?

ANSWER: The 223 Remington has become one of the most popular cartridges and is currently used in a wide range of semiautomatic and manual-action rifles and even handguns, such as the Colt AR-15, Ruger Mini-14, Remington Model 700, Remington XP-100, etc.

QUESTION: What is the Best 223 Ammo?

ANSWER: Just as with comparisons on 5.56 and 223, the term best is subjective. It's centered on your rifle and the way you intend to use it. Many manufacturers produce excellent options tailored to what you're planning to use the rifle for.

QUESTION: What is Green Tip 223 Ammo?

ANSWER: Green Tip 223 ammo is usually a common form of military surplus M855 rounds. These cartridges are often 5.56×45mm NATO rounds and contain a steel bar inside the bullet.

When compared to standard full metal jacket (FMJ) ammo, green tip ammo has greater penetration and can even pierce armored tanks and steel. If your bullet tip is green plastic, not green paint, then it may be a ballistic or polymer tipped specialty bullet, such as Hornady FTX ammo.

QUESTION: How Much does 223 Ammo Cost?

ANSWER: Prices of ammunition fluctuate based on supply availability and demand for the rounds. With 223 ammunition being one of the more popular rounds, it's highly susceptible to those market forces.

In times of higher demand and relative scarcity, the price rises considerably. Price varies per box, but the cheapest method is to purchase in bulk; this greatly reduces the price per round.

QUESTION: Where to buy 223 and 556 Ammo?

ANSWER: Given its popularity, finding 223 ammo is much easier than finding some other rounds. Even in times of increased demand, it's a major staple on ammunition shelves. It can be found at every major ammunition retailer, including online retailers like Ammunition Depot.

QUESTION: Where to buy Bulk 223 Ammo?

ANSWER: While bulk purchases are becoming more popular, that can limit availability among some retailers. For that reason, bulk ammunition purchases are often most easily accomplished through online methods.

Stores and gun shows are often limited in the amount they can carry. Most places selling ammunition can provide bulk in some form, but websites like Ammunition Depot have much greater availability than many physical stores.
