Delving into Corrosive Ammunition
The Corrosive Agent and Its History
To truly grasp the differences, it’s essential to understand what defines corrosive ammunition. Essentially, corrosive ammunition utilizes primer compounds that, upon ignition, leave behind corrosive salts. These salts are the key to the issue. Historically, many countries used corrosive primers because they offered certain advantages, particularly in terms of cost-effectiveness and stability, especially in less technologically advanced times. The chemical composition of the primers, usually containing compounds like potassium perchlorate or potassium chlorate, results in the production of these salts when the primer detonates and ignites the propellant.
When the cartridge is fired, this residue, which is a fine, often microscopic, film, settles within the barrel, the bolt, the action, and other metal components of the firearm. The problem arises because these salts are hygroscopic, meaning they readily absorb moisture from the air. This absorbed moisture then interacts with the metal of the firearm, initiating a corrosive reaction – rust. Over time, this reaction can severely damage the firearm.
The Consequences of Corrosive Residue
Damage to Firearm Components
The impact of corrosive ammunition can be quite significant. The most immediate concern is the formation of rust. Rust, a form of iron oxide, progressively eats away at the metal. In extreme cases, this can lead to several serious problems.
Rust and corrosion can severely damage the barrel, potentially impacting accuracy and, eventually, rendering it unusable. The barrel’s rifling, which imparts spin to the bullet for stability, is particularly vulnerable. Corrosion can pit the rifling, diminishing its ability to properly stabilize the projectile, resulting in inaccurate shots or, in worse cases, barrel failures.
Furthermore, the bolt and action, crucial mechanical components, are also highly susceptible. The buildup of rust can cause these parts to seize or malfunction, potentially leading to jams, failures to fire, or even dangerous malfunctions. The firing pin, a critical element, can become corroded, leading to misfires.
Timeline and Severity of Corrosion
The timeline of damage depends on several factors, including the environmental conditions (humidity, temperature), how promptly the firearm is cleaned, and the inherent resistance of the metal to corrosion. Corrosion can initiate rapidly, especially in humid environments, and it can worsen exponentially if left unaddressed. The effects on an old gun will be more visible, as they generally do not have modern rust-resistant treatments.
Unveiling the Nature of Non-Corrosive Ammunition
Primer Compounds and Their Advantages
In contrast, non-corrosive ammunition is designed to mitigate the risk of corrosion. The critical difference lies in the primer compounds used. Modern non-corrosive ammunition employs different primer compositions, typically using more stable and chemically inert compounds. These primers are designed to leave behind a residue that is much less reactive and does not promote the same corrosive action as the salts from corrosive primers.
This shift to non-corrosive primers has become standard in modern ammunition manufacturing, offering a significant advantage to firearm owners, making the upkeep much easier. Non-corrosive ammo provides a more reliable and user-friendly experience.
Comparing Maintenance and Cleaning Procedures
Cleaning Regimen for Corrosive Ammunition
The cleaning and maintenance requirements are fundamentally different between these two ammunition types.
For corrosive ammunition, swift and thorough cleaning is paramount. The primary goal is to neutralize the corrosive salts before they have a chance to damage the firearm.
The initial step involves using hot water or a specialized solvent designed to neutralize corrosive salts. The hot water helps remove the residue and can assist in dissolving the salts. The cleaning process is more elaborate than usual. The user must make sure all parts of the firearm are properly dissembled and cleaned. This should be followed by a thorough cleaning with a bore brush and appropriate solvents. The solvents help to remove any remaining residue and ensure that the barrel is completely clean. Once the firearm is thoroughly cleaned, lubrication is essential. This creates a protective barrier against rust and further corrosion. Lubricating all moving parts ensures that the firearm operates smoothly.
Cleaning Non-Corrosive Ammunition
For non-corrosive ammunition, while cleaning remains essential, the immediacy and intensity of the cleaning process are less critical. A regular cleaning schedule using standard gun cleaning products is usually adequate. You are generally focusing on removing carbon fouling from the barrel and any other build up. The focus shifts to keeping the firearm running smoothly. Proper lubrication is still important, as it protects against wear and tear and ensures reliable function.
The tools and supplies needed also differ. For corrosive ammunition, you’ll need specific solvents designed to neutralize the corrosive salts, along with a robust set of cleaning brushes and patches. You’ll also benefit from a well-stocked supply of lubricating oil. For non-corrosive ammo, you can typically get by with standard gun cleaning solvents, brushes, patches, and lubricating oil.
Navigating Ammunition Identification and Procurement
Identifying Ammunition Type
Identifying the type of ammunition is the first step towards proper firearm care.
Look for any markings on the ammunition packaging. Many manufacturers clearly label their ammunition as “non-corrosive” or provide a similar indication. Certain historical clues can also be helpful. Surplus ammunition, especially from older military stockpiles, is often corrosive.
You can also find information online from reputable sources such as online gun forums and enthusiast websites. These communities can provide valuable insights and experiences.
Sourcing Ammunition
Sourcing ammunition requires some thought. You can find both types of ammo in many venues, including local gun stores. There are several online retailers. It is important to purchase from reputable sources. Always store ammunition in a cool, dry place away from direct sunlight and children. Never store ammunition in areas with wide temperature swings.
Examining the Advantages and Disadvantages
Pros and Cons of Corrosive Ammunition
Let’s sum up the pros and cons.
Corrosive ammunition can have a significant advantage in terms of cost. In some cases, it can also be widely available. Surplus ammunition often features corrosive primers.
The disadvantages are quite prominent. Corrosive ammo necessitates more rigorous and immediate cleaning and maintenance. Failure to do so can lead to significant damage to the firearm, reducing the reliability of a very valuable tool.
Pros and Cons of Non-Corrosive Ammunition
Non-corrosive ammo, on the other hand, offers a more user-friendly experience. You can clean your firearms less frequently. The risk of corrosion is significantly reduced, which helps extend the life of the firearm.
The disadvantages can involve a higher price point. Availability can also be limited. The cost differences may vary, depending on the caliber and the type of ammunition.
Concluding Thoughts
Understanding the differences between corrosive vs non-corrosive ammo is fundamental for anyone serious about firearm ownership and maintenance. The choice of ammunition directly impacts the longevity and functionality of your firearms. Proper cleaning, maintenance, and knowledge of these differences will lead to a longer life for your firearms, and prevent mechanical malfunctions.
Choosing the right ammunition depends on your individual needs and priorities. If you are dealing with surplus ammo, you need to have a proper plan to care for your weapon. If you prefer a more straightforward approach, the ease of use of non-corrosive ammunition can be a good choice. Take the time to learn about your firearms.
