.38 S&W Brass Cases 100 Count Starline
Starline .38 Short Colt Brass Cases, Bulk Pack of 100 Units
Starline Precision Ammunition Components is dedicated to maintaining the tightest manufacturing tolerances possible on every metallic cartridge case they produce. Each brass case is engineered with exacting standards to ensure consistent performance and reliability for handloaders and shooters specializing in metallic and semi-metallic cartridge reloading.
All Starline brass cases are manufactured strictly within SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, incorporating advanced heat treatment processes and proprietary metallurgical designs. These enhancements significantly improve the structural integrity, tensile strength, and overall longevity of each case, making them ideal for repeated reloading cycles and high-pressure shooting applications.
These cases are made from new, virgin brass with no primer pockets pre-primed, allowing reloaders full control over primer selection and seating. Prior to loading, it is recommended to trim and chamfer the case mouths to ensure optimal bullet seating and consistent chambering performance.
Due to manufacturing tolerances and handling during transportation, case mouths may not always be perfectly concentric or round. To guarantee a uniform and properly sized case mouth, it is advisable to run the cases through an expanding die. This step will round out and slightly flare the case mouth, facilitating smooth bullet seating and preventing bullet deformation during the loading process. Additionally, deburring the case mouth to remove any sharp edges or burrs is essential to avoid damage to the bullet jacket and ensure consistent ballistic performance.
Users may notice discoloration or spotting on the neck and body of new brass cases. This is a normal byproduct of the annealing processa controlled heat treatment performed by the manufacturer. Annealing involves rapidly heating the brass to a precise temperature followed by rapid cooling, which optimizes the cases hardness and ductility. This process enhances the cases ability to securely hold the bullet while allowing the brass to expand and contract during firing and resizing without cracking or losing structural integrity.
The visible stains or marks are harmless residues from annealing and do not affect the performance or safety of the brass cases. These premium Starline .38 Short Colt brass cases offer reloaders a high-quality, durable foundation for precision handloading, ensuring consistent chamber pressures, reliable ignition, and superior ballistic accuracy for revolver cartridges.
