Starline .454 Casull Brass Cases 100 Count
Starline Brass Cases Caliber 454 Casull Bulk Pack of 100 Units
Starline Ammunition is dedicated to maintaining the strictest manufacturing tolerances possible for every metallic cartridge case they produce. Each brass case is engineered with precision to ensure optimal chamber fit, consistent internal volume, and reliable performance under high-pressure conditions typical of the .454 Casull cartridge.
All cases are manufactured within SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, guaranteeing compliance with industry standards for safety and interchangeability. The brass undergoes a specialized heat treatment process designed to enhance case strength, durability, and longevity, essential for repeated reloading cycles and high-stress ballistic applications.
These are new, once-fired, unprimed brass cases made from premium quality, virgin brass. The cases require trimming and chamfering prior to loading to ensure proper cartridge overall length and smooth bullet seating. This preparation step is critical for maintaining consistent chamber pressures and reliable ignition.
Due to manufacturing tolerances and transportation handling, case mouths may not always maintain a perfectly round profile. To achieve optimal bullet seating and crimping, it is recommended to size the case mouth using an expander die. This process will re-round the mouth and slightly flare it, facilitating easier bullet insertion and ensuring consistent neck tension.
Before loading, it is also advisable to deburr and remove any residual flash or burrs from the case mouth to prevent bullet deformation and ensure smooth chambering.
New brass cases may exhibit discoloration or spotting on the neck and body areas. 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 softens the neck and shoulder areas, providing the necessary ductility for proper bullet grip and allowing the case to expand and contract during firing without cracking or splitting.
The visible discoloration is merely a surface residue from this heat treatment and does not affect the structural integrity or performance of the cases. Proper annealing is critical for maintaining case longevity and consistent ballistic performance throughout multiple reloads.
