Choosing the right ammunition is crucial for any shooter, especially when it comes to the popular 5.56 NATO round. While a vast market offers many options, some 5.56 ammo simply doesn't meet the mark. This guide identifies types of 5.56 ammo to avoid, highlighting potential problems and offering insights into making informed purchasing decisions. Understanding these pitfalls can save you money, frustration, and potentially, even injury.
Understanding 5.56 NATO Specifications
Before diving into specific rounds to avoid, it's crucial to understand the specifications of the 5.56x45mm NATO cartridge. Military-grade ammunition adheres to strict standards regarding velocity, accuracy, and reliability. Deviations from these standards can lead to various issues in both civilian and military applications. Key factors include:
- Bullet Weight and Construction: The weight and composition of the projectile significantly affect its ballistic performance. Heavier bullets generally offer better accuracy at longer ranges, while lighter bullets possess higher velocity. Poorly constructed bullets may experience fragmentation or instability.
- Powder Charge: The amount and type of propellant used impact velocity and pressure. Insufficient powder can lead to underpowered rounds, while excessive powder increases the risk of over-pressure, potentially damaging firearms.
- Case Construction: The brass casing must be strong and reliable to withstand the pressures of firing. Poorly constructed cases can lead to malfunctions such as case head separation, a serious safety hazard.
Types of 5.56 Ammo to Avoid:
1. Cheap, "Steel-Cased" Ammunition: While inexpensive, steel-cased ammunition often suffers from significant drawbacks. The steel can be harder on the bore of your firearm, leading to increased wear and tear. Furthermore, the steel cases can be more prone to corrosion, and their performance is often inconsistent, leading to reduced accuracy and reliability. The lacquered finish can also cause fouling in your weapon, necessitating more frequent cleaning.
2. Ammunition with Inconsistent Velocity: High variations in muzzle velocity between rounds within a single batch indicate poor manufacturing quality and inconsistent powder charges. This lack of consistency impacts accuracy and can lead to malfunctions. Look for ammunition with stated velocity tolerances; tighter tolerances signify better quality control.
3. Ammunition with Poorly Constructed Bullets: Damaged, deformed, or poorly constructed bullets are a major concern. Bullets with inconsistent profiles or defects can lead to inaccurate shots, keyholing (the bullet striking the target sideways), or even catastrophic barrel damage. Always inspect your ammunition before use.
4. Overly-Aggressive "High-Pressure" Loads: While seeking high velocity can be tempting, excessively high-pressure loads can place undue stress on your firearm, increasing the risk of component failure. Always ensure your chosen ammunition is appropriate for your specific firearm model. Consult your owner's manual for recommended ammunition specifications.
5. Unknown or Unproven Brands: Stick to reputable ammunition manufacturers with a proven track record of quality and safety. Choosing unfamiliar brands increases the risk of encountering substandard ammunition. Researching reviews and looking for brands favored by experienced shooters can help you make informed decisions.
Choosing Reliable 5.56 Ammo:
Prioritizing quality ammunition is crucial for both accuracy and safety. Focus on reputable brands, check for consistent velocities, inspect ammunition before use, and adhere to the manufacturer's recommended specifications for your firearm. Paying a slightly higher price for quality ammunition will significantly outweigh the potential costs of malfunctions, damaged firearms, or worse. A well-functioning firearm and reliable ammo are essential investments for any serious shooter.
