Factory NEW .300 BLACKOUT Brass - 200 ct

All Starline headstamp yellow brass finish. 

Starline's manufacturing process involves, consistent metallurgy, precise tooling, tight quality control and 40 years of industry experience.  Their brass is 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.  In addition, they anneal their cases between each draw to ensure consistent metallurgy in all lots.  Simply put, they are unwavering in their commitment to quality. 

"The .300 Blackout is based off of a shortened 5.56x45mm case that is necked to .30 caliber. For AR-15 platform rifles and pistols it only requires changing the barrel to go from 5.56 to .300 Blackout. The Blackout's main purpose is to be used at subsonic velocities in suppressed firearms. Many bolt action and single shot rifles are now being produced in this caliber as well." -Starline
