This guide, informed by expert firearm instructor insights, details how to assess ammunition that has been exposed to water. It explains that while brief exposure may not be detrimental, prolonged submersion can lead to misfires due to compromised seals. The guide also provides crucial safety information regarding hang fires, emphasizing muzzle discipline.

Quick Summary

Ammunition exposed to water may still be safe to shoot if the exposure was brief and the ammo is well-sealed. However, prolonged submersion (over 24 hours) can compromise powder integrity, leading to misfires. Military-grade ammo generally offers better moisture resistance due to sealed primers and projectiles.

Frequently Asked Questions

Is ammunition that has gotten wet safe to shoot?

It depends on the duration of exposure and the ammunition's sealing. Brief exposure to water may not ruin standard commercial ammo, but prolonged submersion (24+ hours) can compromise powder integrity, leading to misfires. Military-grade ammo often has better seals.

What are the risks of shooting water-damaged ammunition?

Water-damaged ammunition can result in misfires, light strikes, or hang fires (delayed ignition). Visible corrosion, like green discoloration on brass, indicates significant degradation and potential unreliability. Always prioritize safety and proper handling.

What should I do if I experience a hang fire with ammunition?

If you hear a primer ignite but the shot doesn't immediately discharge (a hang fire), keep the firearm pointed downrange for at least one minute. This allows time for a delayed ignition. After the minute, carefully eject the round.

Does the packaging of ammunition indicate if it's compromised by water?

External packaging damage, like wrinkling on a cardboard box, indicates water exposure but doesn't definitively mean the cartridges inside are ruined. Military ammo often has sealed primers and projectiles, offering better protection against moisture ingress.
