Starline 50 Beowulf Brass

Starline 50 Beowulf is a big, powerful big bore cartridge designed for use in AR style rifles.  The brass case is essentially a lengthened 50 AE (1.650 long) with a rebated 7.62×39 style head.  This particular case is designed to use a large magnum pistol primer. Brass starts with consistent metallurgy, precise tooling, tight quality control, and 30 plus years of experience. 100% of Starline 50 Beowulf brass guaranteed to have flash hole presence and to be of the correct length and diameter. Unlike some competitors, Starline’s brass has the 12.7x42MM headstamp and is vertically drawn, effectively minimizing wall thickness variation.
