300 Blackout (Small Rifle primer) Starline Brass
.Also known as 300 AAC Blackout, .300 BLK, 7.62x35mm
1.356 - 1.360 O.A.L.
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’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.
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.
