Brass cases specifically designed for precision handloading of semi-automatic pistols. These 9x21mm Starline brass casings are engineered to meet the rigorous demands of competitive shooting, tactical applications, and ballistic consistency.
Starline meticulously maintains ultra-tight manufacturing tolerances on every metallic component they produce, ensuring uniformity and reliability essential for high-performance reloading. Each case is crafted with exacting dimensional control to optimize chamber fit and feeding reliability in a wide range of firearm platforms chambered for 9x21mm.
All brass casings are manufactured in strict accordance with SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, guaranteeing compliance with industry standards for pressure containment and dimensional accuracy. Additionally, these cases undergo a proprietary thermal treatment process designed to enhance tensile strength, improve case longevity, and resist deformation during repeated firing cycles.
Constructed from premium new, unprimed brass, these Starline cases provide reloaders with a clean, consistent foundation for precision handloading. Prior to loading, it is essential to trim the cases to the recommended length and chamfer the case mouth to facilitate smooth bullet seating and prevent projectile damage.
Due to manufacturing variances and transportation handling, case mouths may exhibit slight deviations from perfect roundness. To ensure optimal bullet alignment and consistent chambering, it is recommended to size the case mouth using an expander die. This step will re-round and slightly flare the mouth, allowing for easier bullet insertion and improved concentricity.
Deburring and removing any residual flash or burrs from the case mouth is also critical before seating projectiles, as this prevents bullet deformation and ensures consistent seating depth and tension.
Visual surface discolorations or spotting may be present on new brass cases, particularly around the neck and body areas. These marks are the result of the annealing processa controlled heat treatment performed by the manufacturer. Annealing involves rapidly heating the brass to a precise temperature followed by swift cooling, which optimizes the cases hardness and imparts the necessary ductility.
This thermal conditioning allows the case neck to expand and contract reliably during firing and resizing cycles without cracking, thereby extending the service life of the brass. The discoloration is a harmless residue from this annealing process and does not affect the structural integrity or performance of the cases.
