Starline Brass announces its support for the 338 ARC with a new brass ammo casing release. The 338 ARC is designed for suppressed subsonic use, capable of firing heavier .338 caliber bullets that offer more energy than the 300 Blackout while fitting the AR-15 platform, also allowing for supersonic loadings.
Starline Brass states “The 338 ARC was developed to compete with the 300 Blackout and 8.6 Blackout for mainly suppressed subsonic use. It is able to run the heavier .338 caliber bullets like the 8.6 Blackout so it has more energy than the 300 Blackout, but is still able to run in the AR-15 platform unlike the 8.6. It is capable of supersonic loadings as well, but keep in mind that many of the .338” hunting type bullets were designed for the large magnum calibers and may not perform properly on game at the slower velocities. Many companies are putting out bullets designed to expand at the subsonic velocities that would work well in this cartridge for hunting applications.”
