Starline 458 SOCOM Brass

Starline 458 SOCOM Brass starts with consistent metallurgy, precise tooling, tight quality control, and 30 plus years of experience. 100% of Starline 458 SOCOM brass guaranteed to have flash hole presence and to be of the correct length and diameter. Unlike some competitors, Starline’s brass is vertically drawn, effectively minimizing wall thickness variation.

Starline 458 SOCOM brass has been tested at elevated pressures suitable for Magnum Heavy Hunting Loads in adequate gun systems. When loading with black powder, annealing of mouth may be necessary to allow case to properly seal chamber due to lower pressures generated by these loads. Our case is produced very strong to withstand high pressure loads associated with smokeless hunting loads and since the only way to make brass harder is to work the material our only option is to leave them stiffer so the customers can anneal for specific application. See annealing procedure in Commonly Asked Questions, section #4.
