Starline 357 Mag bulk brass is crafted with precision and reliability in mind, utilizing consistent metallurgy, refined tooling, and over 30 years of manufacturing experience. Every case is guaranteed to meet strict standards for flash hole integrity, length, and diameter. Starline’s vertically drawn process ensures minimal wall thickness variation, which results in exceptional uniformity and durability across all lots.
Designed to perform under elevated pressures, this brass is tested for use with heavy Magnum loads in suitable firearms. Whether you’re reloading for revolvers or lever-action rifles, Starline 357 Mag brass provides dependable performance for hunting, sport shooting, or personal defense. If you’re loading black powder rounds, annealing the case mouth is recommended to achieve a proper chamber seal under lower pressures.
Starline deliberately leaves the brass slightly stiffer, giving reloaders the flexibility to anneal according to their specific application. This approach maximizes case life and optimizes performance under demanding conditions. For those looking to fine-tune their loads, detailed annealing procedures are available in section #4 of Starline’s FAQ. When only the best in 357 Mag bulk brass will do, choose Starline.
