While steel-cased ammo offers certain advantages, its physical and material characteristics may influence how well it performs when linked. Understanding whether steel ammo can be linked effectively requires a closer look at the properties of the ammo, the linking mechanisms, and the operational demands of various firearms.

In this article, we’ll explore the considerations surrounding steel ammo and linked feeding systems, shedding light on the factors that affect their compatibility. Whether you’re a casual shooter, a collector, or someone interested in the technical aspects of ammunition handling, this overview will prepare you to delve deeper into the topic and make informed decisions about using steel-cased ammo in linked formats.

Compatibility and Functionality of Linking Steel Ammo

Linking steel-cased ammunition requires careful consideration of both the physical characteristics of the steel cases and the design of the linking system. Steel cases differ from traditional brass in several ways, including hardness, surface finish, and dimensional tolerances. These factors can affect how well steel ammo can be linked and fed through belt-fed weapons.

Steel cases are generally harder and less malleable than brass, which can influence the performance of the push-through or pull-out link mechanisms commonly used in ammunition belts. The steel’s surface finish may also impact the friction between rounds and links, potentially causing feeding issues if not properly matched.

When linking steel ammo, the following aspects are critical:

  • Link Material and Design: Links must be made of a material compatible with steel cases to prevent excessive wear or corrosion. Steel links with appropriate coatings are often used.
  • Dimensional Tolerances: Steel cases tend to have tighter dimensional consistency, but slight variations can still affect how snugly the rounds fit within the links.
  • Linking Method: Pull-out links (such as M13 links) are typically preferred for steel ammunition because they allow the round to be pulled cleanly from the link without relying on deformation.
  • Feeding System Compatibility: The firearm’s feed mechanism must accommodate the slightly different stiffness and surface properties of steel ammo belts to avoid jams.

Properly linked steel ammo can function reliably if these conditions are met, although it often requires specialized equipment or adjustments compared to brass-cased linked ammo.

Techniques for Linking Steel Ammo

Linking steel ammunition involves several techniques tailored to maintain belt integrity and ensure smooth feeding. Unlike brass ammo, which can sometimes be linked manually with moderate effort, steel ammo often demands more precise handling due to its rigidity.

Key techniques include:

  • Using Specialized Linking Machines: Automated or semi-automated linkers designed to handle steel cases apply consistent force, reducing the risk of damaging cases or links.
  • Manual Linking with Care: If done by hand, operators should use tools such as link pliers to minimize deformation and ensure the rounds seat properly within the links.
  • Lubrication and Cleaning: Applying a light film of lubricant or anti-corrosion treatment on links can reduce friction between steel cases and links, improving belt flexibility.
  • Quality Control Checks: Regular inspection of linked belts for tightness and alignment helps prevent feeding malfunctions.

These techniques help maintain the structural integrity of the ammo belt and ensure reliable operation in belt-fed weapons.

Performance Considerations When Using Linked Steel Ammo

The use of linked steel ammunition can influence weapon performance in several ways. While steel-cased ammo often offers cost savings and availability advantages, it may affect feeding reliability and maintenance requirements.

Some performance considerations include:

  • Increased Wear on Links and Feed Mechanisms: The hardness of steel cases can accelerate wear on links and firearm feed components, necessitating more frequent maintenance.
  • Potential for Increased Jamming: Improperly linked steel ammo or mismatched links can lead to feeding issues due to higher friction or improper round alignment.
  • Weight and Handling: Steel ammo belts may weigh slightly more than brass-cased equivalents, impacting handling during extended use.
  • Corrosion Resistance: Steel cases and links are more susceptible to rust if not properly treated, which can degrade performance over time.

Balancing these factors is essential for users who opt to link steel ammo, especially in high-volume firing scenarios.

Linking Steel Ammo: Feasibility and Considerations

Linking steel-cased ammunition is technically possible but comes with specific challenges and considerations that differ from traditional brass-cased rounds. The primary factors influencing the linking process include the physical properties of steel cases, the type of link system used, and the intended firearm platform.

Steel-cased ammo tends to be harder and less malleable than brass, which affects how the cartridges interact with disintegrating or non-disintegrating links. This difference can impact the ease of linking, the durability of the linked belt, and the reliability of feeding in automatic weapons.

Key Factors Affecting the Linking of Steel Ammo

  • Material Hardness: Steel cases are more rigid, which can cause increased wear on link components or difficulty in achieving a secure crimp.
  • Link Type Compatibility: Most standard disintegrating links (e.g., M13 links) are designed with brass cases in mind; steel cases may require slight modifications or specialized links.
  • Coating and Surface Treatment: Many steel cases are coated with lacquer or polymer to reduce corrosion, which can influence how well links grip the case rim.
  • Dimensional Tolerances: Steel ammo sometimes has tighter or slightly different dimensions than brass, affecting the fit within the link’s locking points.
  • Feeding Reliability: The interaction between steel cases and links can affect the smoothness of feeding, especially in high cyclic rate firearms.
