What to Do with Firearms and Ammunition Affected by Flood Waters

You do not have to be a victim of a hurricane to experience the destructive effects of flooding. A broken pipe, ruptured water heater, or a sump pump that goes out during a storm is enough to do it in some areas. In any case, flooding and firearms are not only a bad mix, it can be a financial disaster. This leaves firearms owners who have seen their guns and stored ammunition submerged by flood waters wondering whether their firearms and ammunition can be salvaged and used safely. Fortunately, the National Shooting Sports Foundation and Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) have the answer.

.223 vs. 5.56: Which Ammunition Is Safe for My AR-15?

Using commercial .223 cartridges in a 5.56-chambered rifle should work reliably, but generally will not be as accurate as when fired from a .223-chambered gun due to the excessive leade. There always seems to be a lot of confusion over the difference between a .223 and a 5.56 chamber. I often receive questions asking if someone can shove 5.56 ammo into their new AR-15. The quick answer is maybe. Just because a gun has .223/5.56 scribed on the barrel, does not mean it can handle either piece of ammunition equally.
