Should You Put Gun Oil in the Barrel? A Comprehensive Guide
The question of whether or not to put gun oil in the barrel is a common one among firearms enthusiasts, sparking debates and varying opinions. The short answer is: generally, no, you shouldn't routinely oil the inside of your gun barrel. However, there are nuances and exceptions to this rule, which we'll explore in detail.
Why You Shouldn't Oil the Barrel (Most of the Time)
The primary reason to avoid oiling the inside of your gun barrel is that it can negatively impact accuracy and potentially damage your firearm. Here's why:
-
Fouling Accumulation: Gun oil can attract and hold onto powder residue and other fouling, creating a gummy buildup inside the barrel. This residue can interfere with the bullet's smooth passage, leading to decreased accuracy and potentially causing damage to the rifling. Cleaning the barrel thoroughly after each use is far more effective at preventing fouling.
-
Increased Pressure: Excess oil can build up pressure within the barrel, potentially causing malfunctions or even dangerous pressure spikes.
-
Reduced Velocity: The extra friction from oil residue can slightly reduce the projectile's velocity. While this might seem negligible, in precision shooting, even small variations can impact accuracy.
-
Carbon Build-up: Oil mixed with carbon residue creates a stubborn varnish-like substance that is significantly more difficult to remove than either component alone.
When (and How) You Might Oil the Barrel (Rare Exceptions)
There are very limited situations where a tiny amount of oil might be considered, but even then, it's a delicate procedure requiring precise application and caution:
-
Storage in Extreme Conditions: If you're storing your firearm for an extended period in extremely humid or corrosive environments, a very light coat of oil on the bore might offer some protection against rust. However, this is generally only recommended for long-term storage and should be done sparingly. A gun safe with a desiccant is a far better solution for humidity control.
-
Break-in Period (Some Firearms): Some manufacturers recommend a very light lubrication of the barrel during the initial break-in period of a new firearm. This is rare and should only be done following the manufacturer's specific instructions.
Proper Gun Cleaning and Maintenance
Instead of oiling the barrel, focus on proper cleaning and maintenance. After each use, thoroughly clean your firearm using a bore brush and appropriate cleaning solvents to remove powder residue and fouling. A properly cleaned barrel will function optimally without the need for internal lubrication.
Focus on External Lubrication
Proper lubrication is crucial for your firearm's longevity and smooth operation, but this should be focused on the external moving parts like the action, trigger mechanism, and slide (if applicable). Use a high-quality gun oil designed for firearms to lubricate these areas.
In Conclusion:
While there are very rare exceptions, regularly oiling the inside of your gun barrel is generally unnecessary and can be detrimental to your firearm's performance and longevity. Prioritize thorough cleaning and proper external lubrication for optimal results and safe firearm handling. Always consult your firearm's owner's manual for specific maintenance recommendations.
