How to Tell if Ammo is Bad
When it comes to shooting, having reliable and functioning ammunition is crucial for a safe and successful outcome. Bad ammo can cause a variety of issues, from inconsistent performance to even damage to your firearms. In this article, we’ll provide you with the necessary steps to determine whether your ammo is good or bad, and how to identify common signs of worn-out or defective cartridges.
Why is Bad Ammo a Concern?
Bad ammo can cause numerous problems, including:
• Inconsistent Performance: Ammunition that is not manufactured to specifications can exhibit erratic behavior, such as inconsistent velocity, accuracy, or reliability.
• Equipment Damage: Poor-quality or damaged ammo can cause premature wear on your firearms, potentially leading to costly repairs or even catastrophic failures.
• Safety Risks: Using defective or corroded ammo can increase the risk of accidental discharges, injuries, or property damage.
• Misfires and FTEs: Bad ammo can result in misfires, FTEs (failure to eject), or other reliability issues that can compromise the safety and performance of your firearm.
How to Identify Bad Ammo
When examining your ammunition, pay attention to the following visual cues:
- Color: Brown or copper-tinted primers indicate improper storage, handling, or exposure to heat. Discoloration can also indicate the use of poor-quality primers or incorrect ignition.
- Cracks: Visible cracks in the casing, primer pocket, or crimp indicate weakened or compromised structural integrity, making the ammo potentially unsafe to fire.
- Dents: Dents or excessive crimping can lead to unreliable extraction, damage to your firearm, or even cause misfires.
- Casing Wall Thickness: Check for uneven or inconsistent wall thickness. Thin spots or excessive compression can lead to premature cartridge separation, which can result in FTEs, misfires, or damaged firearms.
- Mildew or Mold: The presence of mold or mildew on the casing or powder indicates storage conditions that are too humid, which can affect cartridge integrity.
Tests for Reliability and Performance
Conduct the following tests to determine the reliability and performance of your ammunition:
- Chamber Press Check: Load the chamber of your firearm and press the action. Repeat this process multiple times. If the chamber becomes difficult to close or feels "stuck," the ammo may be too swollen or improperly seated.
- Cyclic Reliability Test: Cycle the action repeatedly, chambering and ejecting a cartridge each time. Pay attention to:
• FTEs (Failure to Eject): If more than one or two rounds fail to eject, it may indicate the ammo is too damaged or worn.
• Misfires: Record the number of misfires or failed firings.
• Reliability Index: Create a rating system to evaluate the overall performance and reliability of your ammunition. - Firing Testing: Test a batch of ammo from each manufacturer, using your favorite load development rifle or target pistol. Note:
• Velocity Consistency: Monitor velocity consistency throughout a batch, as large variations may indicate poor-quality components.
• Group Size and Accuracy: Observe the group size and accuracy, as excessive spreading or irregular patterns can signal bad ammo.
Troubleshooting Common Issues
If you encounter problems with your ammo, consider the following solutions:
- Inspection: Visual inspection may reveal hidden damage or imperfections in the cartridge.
- Storage and Handling: Improper storage, handling, or exposure to environmental factors may have affected the quality of your ammo.
- Cleanliness and Lubrication: Inconsistent cleanliness or lubrication of the barrel, breech, or other internal components may influence ammo performance.
- Maintenance and Calibration: Ensure your firearm is properly maintained, calibrated, and functioning as intended to eliminate any possible causes of misfires, FTEs, or reliability issues.
- Replace or Re-Move: Consider replacing suspect or damaged ammo or consulting a firearms professional for guidance on the best course of action.
Conclusion
To ensure reliable performance and optimal shooting results, it is essential to regularly inspect, test, and evaluate your ammunition. By recognizing visual signs of bad ammo and conducting simple tests, you can identify and address issues before they compromise your firearms or safety. Remember, consistent and quality ammunition is vital for optimal performance and longevity of your firearms.
