Starline 357 Sig Brass Cases, Bulk Pack of 100 Units
Starline Precision Ammunition Components is dedicated to maintaining the tightest manufacturing tolerances possible on every metallic case they produce. Each 357 Sig brass cartridge case is engineered with exacting precision to ensure consistent chambering, optimal ballistic performance, and reliable feeding in semi-automatic pistols.
All Starline brass cases are manufactured strictly within SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, guaranteeing compatibility and safety across all firearms chambered for the 357 Sig cartridge. The cases undergo specialized heat treatment processes designed to enhance tensile strength, durability, and longevity under repeated firing and reloading cycles.
These cases are made from premium new, unprimed brass, free from any prior primer pockets or crimps, providing reloaders with a clean slate for custom primer seating and powder charges. Prior to reloading, it is recommended to trim the cases to the proper length and chamfer and deburr the case mouths to facilitate smooth bullet seating and prevent jacket damage during assembly.
Due to manufacturing tolerances and potential handling or transport effects, the case mouths may not always maintain a perfectly circular profile. To ensure proper bullet seating and consistent neck tension, it is advisable to size the case necks using an expander die. This step will also help to slightly flare the case mouth, allowing for easier bullet insertion and improved neck tension retention.
Reloaders should also inspect the case mouths for any burrs or sharp edges and remove them as necessary to avoid bullet jacket damage and ensure reliable chambering and cycling.
New brass cases may exhibit discoloration or spotting on the neck and body surfaces. This is a normal result of the annealing processa controlled heat treatment performed by the manufacturer involving rapid heating to a precise temperature followed by swift cooling. Annealing softens the case neck and shoulder areas, providing the optimal balance of hardness and malleability needed to securely hold the projectile while allowing expansion and contraction during firing and resizing.
The visible discoloration is merely a residue of this annealing process and does not affect the structural integrity or performance of the brass cases. Proper cleaning and polishing prior to reloading can remove most surface marks if desired.
