As part of our Siege Ammo .223/5.56 Varmint Series, this round features the 55-grain GameKing projectile by Sierra combined with a factory new Starline Brass case.
The Sierra Gameking bullet has a spitzer boat tail provides exceptional accuracy and a flat trajectory.
Every round is loaded into a Boxer-primed brass case. These cases are new-production and reloadeable.
*NOTE: Due to component availability, the case is headstamped as 5.56 NATO from Starline. Per Starline's website (www.starlinebrass.com), "Starline’s 5.56x45mm brass is identical to Starline’s .223 Remington brass except for a slight change in the metallurgy making it harder at the base of the case." This ammunition has been designed to perform in both .223 and 5.56 barreled firearms. Testing has been conducted in both .223 Bolt Action and 5.56 AR rifles with tremendous results.
