Whether you stash your gun or rifle in the back of a closet, in the pickup truck console or an in-ground cache, taking proper steps to prevent gun barrel rust is a must – particularly if you’re using corrosive ammunition.
Many a gun lover has endured the misery of pulling their firearm from the case, only to discover that beautiful blue or matte black finish has been marred by creeping rust and/or corrosion. Even the U.S. Military has had issues with failure to prevent gun barrel rust, erosion and wear – particularly with long caliber gun barrels. In a now-unclassified report, the U.S. Army reported the negative impact of gun barrel wear and erosion can include:
- Reduction of muzzle velocity
- Greater risk of inaccuracy
- Increase of dispersion
- Unstable projectile flight
- Damage to other sensitive components
- Hastening of barrel fatigue (resulting from surface defects in both the bore and combustion chamber)
The report indicated that while these things might not necessarily be dangerous to anyone using the gun, they could be extremely hazardous to “friendly personnel located downrange or near the intended target.” That’s a big reason why the military takes special precaution to prevent gun barrel rust – and so should you.
