What to Do with Firearms and Ammunition Affected by Flood Waters
NEWTOWN, Conn., Sept. 11, 2017 : Firearms owners who have seen their guns and stored ammunition submerged by flood waters in storm-wracked areas are probably wondering if their firearms and ammunition can be salvaged and safely used.The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and National Shooting Sports Foundation (NSSF) point to two helpful documents containing guidelines to assist gun owners in making sound decisions related to safely handling and treating or disposing of these items, emphasizing to always err on the side of caution and safety.
SAAMI, founded in 1926, is an organization that creates and publishes industry standards on firearms and ammunition. NSSF is the trade association for the firearms and ammunition industry.
The SAAMI document "Guidance on Firearms That Have Been Submerged or Exposed to Extensive Amounts of Water" points out two major concerns about firearms that have been exposed to water: parts susceptible to moisture and rust damage such as metal parts, wood stocks and grips, and optics; and, secondly, infiltration of the action, barrel and safety systems by grit, silt and other foreign debris.
Always unload firearms before beginning any treatment process.
It's important to limit moisture and corrosion damage to the component parts of the firearm. This can be accomplished by disassembling the component parts and using up to two coats of a moisture-displacing lubricant such as Hoppes #9 MDL or WD-40 to clean and stabilize the parts while, importantly, following the product's directions so as not to damage, for instance, plastic or synthetic parts. Another tip is to allow wood stocks and grips to air-dry and not be force dried by exposure to heat.
The document emphasizes that once the firearm has been thoroughly dried, consideration must be given to having the firearm inspected and serviced by the manufacturer, an authorized service center or a qualified gunsmith before putting the firearm back in service.
Dealing with Submerged Ammunition
To help firearms owners determine what to do with ammunition that has been affected by water and moisture, SAAMI offers another helpful document, "Guidance on Ammunition That Has Been Submerged in Water."
Discussed are differences in moisture resistance between centerfire, rimfire and shotshell ammunition, and potential hazards associated with "drying out" cartridges, including possible deterioration and damage to cartridges due to drying methods.
Another serious hazard that could result from using compromised ammunition is the potential for a bore obstruction due to partial ignition of either the priming compound or the propellant powder charge, or both. Firing a subsequent round through an obstructed barrel can result in bodily injury, death and property damage.
SAAMI provides the following cautionary conclusion: "It would be impossible to ascertain for certain the extent of the deteriorating affect, if any, the water may have had on each individual cartridge. Therefore, the safe answer is that no attempt be made to salvage or use submerged ammunition. The ammunition should be disposed of in a safe and responsible manner.
