25-20 WCF Starline Brass Cases 100 pcs
Starline Brass Cases Caliber 25 - 20 WCF, Box of 100 Units (Bulk Packed)
Starline Precision Brass is engineered with meticulous attention to dimensional tolerances, ensuring each metallic cartridge case meets the highest standards demanded by competitive shooters and reloaders alike. Manufactured with exacting adherence to SAAMI specifications, these cases undergo specialized heat treatment processes designed to enhance structural integrity, tensile strength, and overall durability during repeated firing cycles.
Constructed from premium new, unprimed brass, these cases provide an optimal foundation for custom handloading. Reloaders should perform trimming and chamfering operations prior to powder charging to guarantee consistent case length and smooth bullet seating, which are critical for achieving precise chambering and ballistic performance.
Due to manufacturing variances and handling during shipment, case mouths may exhibit slight deviations from perfect roundness. To ensure reliable bullet retention and optimal neck tension, it is recommended to size the case necks using an expander die. This step will uniformly round the case mouth and slightly open the neck diameter, facilitating seamless bullet insertion and preventing projectile deformation.
Reloaders should also inspect and remove any burrs or flash from the case mouth after trimming to avoid seating issues and ensure consistent crimping. Proper case preparation is essential for maintaining safe chamber pressures and maximizing accuracy in metallic cartridge reloading.
Surface discolorations or spotting may be visible on the neck and body of these 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 imparts the necessary hardness to securely hold the bullet while providing sufficient neck elasticity to accommodate expansion and contraction during firing and resizing cycles.
These annealing marks are purely cosmetic and do not affect the performance or longevity of the brass cases. Utilizing Starlines high-quality brass ensures consistent reloads with enhanced case life, making them an excellent choice for precision shooters and metallic cartridge reloaders seeking reliability and performance in every round.
