.45 ACP Brass Cases Starline 100 Count
Starline Brass Cases Caliber .45 ACP - Bulk Pack of 100 Units
Starline Precision Ammunition Components is dedicated to manufacturing brass casings with the tightest possible tolerances, ensuring each metallic piece meets rigorous quality standards essential for reliable reloading and consistent ballistic performance.
All Starline .45 ACP brass cases are produced strictly within SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) specifications, incorporating specialized heat treatment processes and advanced metallurgical designs to enhance case strength, durability, and longevity under repeated firing cycles.
These cases are made from new, virgin brass without any primer pockets pre-primed, providing reloaders with pristine, uncontaminated material ideal for precision handloading applications.
Before reloading, it is recommended to trim and chamfer the case mouths to ensure optimal bullet seating and to prevent damage to the projectile during the loading process.
Due to manufacturing variances and transportation handling, the case mouths may occasionally exhibit slight deviations from perfect roundness. To guarantee proper bullet alignment and reliable chambering, it is advised to size the cases using an appropriate expanding die. This step will re-round and slightly flare the case mouth, facilitating smooth bullet insertion and consistent crimping.
Additionally, deburring the case mouths and removing any residual burrs or sharp edges is crucial prior to loading to avoid bullet deformation and ensure safe chamber pressures.
Users may observe discoloration or spotting on the neck and body of new brass cases. This is a normal result of the annealing process performed by the manufacturer, which involves rapidly heating the brass to a precise temperature followed by quick cooling. Annealing optimizes the hardness and ductility of the brass, allowing the case neck to expand and contract effectively during firing and resizing cycles without cracking or losing structural integrity.
The visible stains are harmless residues from this thermal treatment and do not affect the performance or safety of the brass cases during reloading or shooting.
