Q Boom Box 8.6 Blackout

810152961704

From Google: The 8.6 Blackout (8.6 BLK) is a rifle cartridge developed by Q, LLC, led by Kevin Brittingham, introduced around 2022, evolving from the success of the 300 Blackout to offer more power for the larger AR-10 platform. It uses a shortened 6.5 Creedmoor case necked up to .338 caliber, designed to fire heavy bullets, excelling with suppressors and short barrels by using a fast 1:3 twist rate for high spin, creating massive wound channels even subsonically, making it ideal for hunting and tactical use where power and stealth are key.
