Product Description

Steel cartridge cases are a cost-effective alternative to traditional brass cases for both small and medium-caliber ammunition. While brass is typically favored for its reliability and reloadability, steel is widely used for high-volume, general-purpose ammunition, especially in military applications. Steel-cased ammunition is generally intended for high-volume, low-importance shooting, such as practice and recreational target shooting, where cost is the main priority. 

Features/Roles/Variants of the product
Steel is more susceptible to rust than brass. To prevent corrosion during storage and handling, steel cases are coated with a protective layer, typically a polymer or lacquer.
While effective, this coating can sometimes flake or build up in the chamber, potentially causing malfunctions.
Unlike brass, which expands to seal the chamber and then contracts slightly for easy extraction, steel is less elastic.
The insufficient expansion can allow more gas and unburned powder to blow back into the action, causing increased fouling and a "dirtier" weapon.
Since steel does not contract as well, it can remain stuck to the chamber walls. This increases the work required by the firearm's extractor and can lead to extraction failures, especially in weapons with tight tolerances not designed for steel cases.
The hardness of steel relative to brass can cause accelerated wear on certain firearm components over the long term. This is most notable on the extractor, which must work harder to pull the rigid steel case from the chamber.
Some steel-cased rounds also use bi-metal jackets, which can cause faster barrel throat erosion.
For militaries that melt down and recycle used cartridge cases, steel is abundant.
However, unlike brass, which can be reloaded by individuals many times, steel cases are generally not considered reloadable due to their rigidity and tendency to fatigue.
