Starline Brass Cases for .357 Magnum, Bulk Pack of 100 Units (Loose Packed)
Starline Precision Brass is engineered with meticulous attention to dimensional tolerances, ensuring each metallic cartridge case meets the highest standards required for reliable reloading and consistent ballistic performance. Manufactured with exacting adherence to SAAMI specifications, these .357 Magnum brass cases undergo specialized heat treatment processes designed to enhance structural integrity, tensile strength, and overall longevity under repeated firing cycles.
Constructed from premium new, unfired brass, these cases arrive without primers installed, providing reloaders with a clean slate for custom priming and powder charges. Prior to loading, it is recommended to trim and chamfer the case mouth to ensure optimal bullet seating and prevent jacket damage during assembly.
Due to manufacturing tolerances and transportation handling, the case mouths may exhibit slight deviations from perfect roundness. To guarantee a uniform, concentric case mouth, it is advisable to run the cases through an expander die. This operation will not only round the case mouth but also slightly flare it, facilitating smooth bullet insertion and consistent crimping.
Reloaders should also inspect the case mouths for any residual burrs or sharp edges and deburr as necessary to avoid bullet jacket deformation and ensure safe chambering in semi-automatic or revolver platforms.
Surface discoloration or spotting may be present on the neck and body of these new brass cases. This is a normal byproduct of the annealing processa controlled thermal cycle involving rapid heating to a precise temperature followed by swift cooling. Annealing imparts the ideal balance of hardness and malleability to the brass, allowing the case neck to securely hold the projectile while accommodating expansion and contraction during firing and resizing operations.
Such annealing marks do not affect the structural integrity or performance of the cases and are considered standard in high-quality reloadable brass manufacturing.
