9mm Para Starline Brass Cases - 100 Pieces
Starline 9mm Parabellum Brass Cases, Bulk Pack of 100 Units
Starline Precision Ammunition Components is committed to manufacturing brass casings with the tightest possible tolerances, ensuring each metallic cartridge case meets rigorous industry standards. These 9mm Luger (9x19mm Parabellum) brass cases are engineered for optimal performance in both reloading and live-fire applications.
All Starline brass casings are produced strictly within SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, guaranteeing consistent dimensions and reliable chambering. The cases undergo specialized heat treatment processes designed to enhance tensile strength and durability, extending the service life of each casing through multiple reload cycles.
Crafted from new, unfired brass with no primer pockets pre-primed, these cases require trimming and chamfering prior to loading to ensure proper bullet seating and reliable ignition. Reloaders should carefully inspect each case mouth, as manufacturing and shipping can occasionally cause slight deformation or out-of-round conditions.
To achieve a perfectly round case mouth, it is recommended to run the cases through a neck-expanding die. This step not only ensures uniform neck diameter but also facilitates smooth bullet seating by slightly flaring the case mouth. Additionally, any burrs or sharp edges should be removed through deburring tools to prevent damage to projectiles and ensure consistent chamber pressure.
New brass cases may exhibit discoloration or spotting on the neck and body surfaces. This is a normal result of the annealing processa controlled thermal cycle involving rapid heating to a precise temperature followed by swift cooling. Annealing optimizes the brass hardness, providing the ideal balance between strength and flexibility. This metallurgical treatment allows the case neck to expand and contract during firing and resizing without cracking, thereby improving reloadability and overall cartridge integrity.
The visible stains or color variations are harmless residues from annealing and do not affect the performance or safety of the brass cases. These premium Starline 9mm Parabellum brass casings are ideal for precision handloaders seeking consistent, high-quality components for semi-metallic and metallic cartridge reloading.
