Starline Brass Cases for .45-70 Government – Bulk Pack of 100 Units

Starline Precision Brass is engineered with meticulous attention to dimensional tolerances, ensuring each metallic cartridge case meets the highest standards for ballistic consistency and reliability. Manufactured to exacting SAAMI specifications, these .45-70 Government cases undergo specialized heat treatment processes designed to enhance structural integrity, tensile strength, and overall durability for repeated reloading cycles.

Constructed from premium new, virgin brass without primer pockets, these cases provide an optimal foundation for custom handloading. Reloaders are advised to trim and chamfer the case mouths prior to bullet seating to ensure uniform case length and smooth projectile insertion, critical for achieving consistent chamber pressures and optimal ballistic performance.

Due to manufacturing variances and transportation handling, case mouths may exhibit slight deviations from perfect roundness. To guarantee proper bullet seating and reliable chambering, it is recommended to run the case mouths through an expander die. This operation will re-round and slightly flare the neck, facilitating smooth bullet seating and preventing bullet deformation during loading.

Reloaders should also inspect and deburr the case necks to remove any residual burrs or sharp edges that could impede bullet alignment or cause seating inconsistencies. Proper neck preparation is essential for maintaining consistent neck tension and ensuring repeatable accuracy.

It is common to observe discoloration or spotting on the neck and body of new brass cases. This is a normal byproduct of the annealing process performed by the manufacturer, which involves rapidly heating the brass to a precise temperature followed by rapid cooling. Annealing imparts the necessary hardness and elasticity to the case neck, allowing it to securely hold the projectile while accommodating expansion and contraction during firing and resizing.

These annealing marks do not affect the performance or longevity of the brass and are indicative of high-quality manufacturing practices aimed at optimizing case life and reloadability for precision shooters and metallic cartridge enthusiasts.
