Understanding the 5.7x28mm Cartridge: A Closer Look
Technical Specifications
The 5.7x28mm cartridge, developed by FN Herstal, boasts a design. It’s a bottleneck cartridge, where the bullet is narrower than the case. This high-velocity round, often exceeding a thousand feet per second depending on the specific load. Bullet weights available in the 5.7x28mm range from relatively light projectiles to slightly heavier options.
Advantages and Disadvantages
One major advantage is its high velocity, leading to a flat trajectory. The low recoil facilitates faster follow-up shots. The compact size of the cartridge allows for higher magazine capacities. One challenge is limited ammunition availability and potentially higher cost. Controversy surrounds the performance in self-defense situations, and the high velocity can lead to over-penetration.
Key Considerations for Self Defense Ammo Selection: Making Smart Choices
Purpose and Objectives
Consider your primary purpose. Is it primarily for home defense, concealed carry, or some other scenario? The ideal ammunition may vary depending on the anticipated use.
Terminal Ballistics
Penetration is key to reaching vital organs. Insufficient penetration means the round might not be effective. Expansion and fragmentation are also important. Expanding bullets increase the diameter of the wound channel. Fragmentation creates multiple wound channels.
Reliability
Your ammunition must function flawlessly every time you pull the trigger. This means choosing ammunition from reputable manufacturers and thoroughly testing it in your firearm.
Gun and Ammunition Compatibility
Not every gun is compatible with every type of ammunition. Always follow the gun’s manufacturer instructions regarding the acceptable ammunition.

Testing and Training: Preparing for Action
Range Testing
Range-test any ammunition you intend to use for self-defense. This involves firing multiple rounds at various distances. Test for accuracy, reliability, and point of impact. If you notice any malfunctions, stop and switch to a different round. Never carry ammunition that you have not personally tested.
Training
Practice with your chosen ammunition regularly. Shooting drills will build confidence and improve accuracy. Practice your draw, shooting from different positions, and clearing potential malfunctions.
