Why Reloaders Choose Starline Brass
Starline is renowned for manufacturing high-quality cartridge brass in the USA. Each .357 Rem Max case is drawn from high-grade alloy, given controlled annealing for consistent hardness, and inspected to tight tolerances. That attention to detail translates into:
Superior dimensional consistency for reliable feeding and chambering.
Excellent ductility and neck life, which keeps shoulder and neck integrity through multiple reloads.
Clean, burr-free flash holes and uniform primers pockets (unprimed product requires priming by the reloader), minimizing variability in ignition.
