Choosing the right ammunition is crucial whether you're a seasoned firearms enthusiast or a first-time buyer. This comparison dives deep into the differences between .223, .380, and 5.56 ammunition, helping you understand their respective strengths and weaknesses in various applications, from self-defense to target shooting and hunting (where applicable).
Understanding the Basics: Caliber and Cartridge
Before we compare, let's clarify a common point of confusion: .223 and 5.56 are often used interchangeably, but they aren't precisely the same. While both are rifle cartridges, they have slightly different chamber specifications, leading to variations in pressure and accuracy depending on the firearm. The .380 ACP, on the other hand, is a pistol cartridge significantly smaller and less powerful than the rifle rounds.
.223 Remington
- Caliber: .223
- Type: Rifle cartridge
- Common Applications: Target shooting, hunting small game (depending on regulations), and some self-defense scenarios.
- Pros: Relatively inexpensive, readily available, accurate, and effective for its intended purposes. Lighter recoil than larger calibers.
- Cons: Limited stopping power compared to larger calibers, potentially less effective for self-defense against larger threats.
.223 vs 5.56: Key Differences
While often used synonymously, .223 Remington and 5.56 NATO cartridges differ subtly yet importantly:
- Chamber Pressure: 5.56 NATO operates at higher chamber pressure, meaning it generates more energy.
- Case Dimensions: Minor differences in case dimensions exist, making it generally unsafe to fire 5.56 ammo in a .223 chamber (though some .223 rifles can handle 5.56—check your firearm's manual).
- Accuracy: Differences in accuracy can vary based on firearm and ammo, but it's not always predictable.
5.56 NATO
- Caliber: 5.56x45mm
- Type: Rifle cartridge
- Common Applications: Military applications, law enforcement, hunting, and target practice.
- Pros: Higher velocity than .223, potentially greater stopping power, effective range.
- Cons: More powerful recoil than .223, can be more expensive than .223, potentially unsuitable for smaller-framed shooters due to recoil.
.380 ACP (Automatic Colt Pistol)
- Caliber: .380
- Type: Pistol cartridge
- Common Applications: Self-defense (concealed carry), target shooting.
- Pros: Small and easy to conceal, relatively low recoil, manageable for smaller-framed individuals.
- Cons: Lower stopping power than larger calibers, shorter effective range, limited penetration. Ammunition choices can be a factor.

| Effective Range | Moderate | High | Short |
| Stopping Power | Moderate | High | Low |
| Concealability | Not Applicable | Not Applicable | High |
| Cost | Moderate | Moderate-High | Moderate |
Choosing the Right Ammunition
The "best" ammunition depends entirely on your intended use.
-
Self-Defense: For concealed carry, the .380 offers concealability. However, consider larger calibers like 9mm or .45 ACP for increased stopping power. For home defense, a rifle cartridge like .223 or 5.56 offers significant reach and stopping power, but requires responsible storage and handling.
-
Hunting: .223 or 5.56 are suitable for small game, but larger calibers are often necessary for bigger animals. Always check local hunting regulations.
-
Target Shooting: All three calibers are suitable for target practice, offering a variety of cost and power options.
