9mm Makarov Brass Cases 9x18 Starline 100 pcs
Starline 9mm Makarov (9x18) Brass Cases Bulk Pack of 100 Units
Starline Precision Ammunition Components is dedicated to manufacturing brass cases with the tightest possible tolerances, ensuring each metallic cartridge case meets rigorous dimensional and quality standards essential for reliable reloading and consistent ballistic performance.
All Starline brass cases are produced strictly within SAAMI (Sporting Arms and Ammunition Manufacturers Institute) specifications, guaranteeing compatibility and safety across a wide range of firearms chambered in 9x18mm Makarov. These cases undergo specialized heat treatment processes designed to enhance the metallurgical properties, increasing tensile strength, durability, and longevity under repeated firing and reloading cycles.
Constructed from premium new (once-fired) high-quality brass, these cases arrive unprimed and require trimming and chamfering prior to loading. Proper case preparationincluding neck sizing and deburringis critical to ensure optimal chamber fit, consistent bullet seating, and reliable ignition.
Due to manufacturing tolerances and transport handling, case mouths may occasionally exhibit slight ovality or deformation. Reloaders are advised to run these cases through a neck expander die or a dedicated case mouth sizing die to restore perfect concentricity and roundness. This step facilitates smooth bullet seating and prevents bullet deformation during the reloading process.
Visual surface imperfections such as discoloration or spotting on the neck and body of the brass cases are normal and result from the annealing process. Annealing involves rapidly heating the case neck and shoulder area to a precise temperature followed by controlled cooling, which softens the brass to the ideal hardness. This metallurgical treatment allows the case neck to expand and contract during firing without cracking, maintaining consistent neck tension for secure bullet retention and reliable chambering.
These annealing marks are purely cosmetic and do not affect the structural integrity or performance of the brass. Reloaders can expect excellent case life and consistent ballistic results when using Starline 9x18mm Makarov brass, making it an optimal choice for precision handloading and semi-metallic cartridge assembly.
