New Rifle Brass from Starline for the AR-15

Starline Brass has recently announced the addition of .300 Blackout to their growing line-up of quality rifle brass, which will soon include .450 Bushmaster, .243 Win, .223 Rem, 6.5 Creedmoor (small and large primer pockets), 7 mm-08 and .260 Rem.

Starline’s new .300 Blackout rifle brass is produced with the same rigorous quality control standards that Starline has become known for. It is now available at half the price of comparable cases. You can order Starline’s .300 Blackout cases direct from the factory by visiting their website.

The .300 Blackout was introduced in 2009 by Advanced Armament Corporation (AAC) for use in the AR-15 platform. Any standard 5.56 AR-15 can easily be converted to .300 Blackout by changing the barrel. Its main purpose is to be loaded at subsonic velocities for use with a suppressor.

The .300 Blackout is the first SAAMI standardized round based on the .300/.221 Fireball wildcats, though the Blackout was designed to be built off of the 5.56 case.

With a wide selection of bullets available in .30 caliber, the .300 Blackout is suitable for taking game as large as whitetail deer, when loaded at supersonic velocities. The adjustability of the AR-15 platform and the low recoil of this round make it an excellent choice for smaller stature hunters.

The popularity of the .300 Blackout cartridge has led to it being offered in many bolt action and single shot rifles, which allows it to be loaded at subsonic velocities with any bullet weight, without concerns about cycling.
