Is the Ultimate Do-It-All Rifle a .300 Blackout?
This video from T.REX ARMS evaluates the .300 Blackout cartridge's viability as an 'all-around' rifle round. While acknowledging its effectiveness in specific Personal Defense Weapon (PDW) roles and for suppressed, close-quarters applications, the assessment concludes it falls short as a true do-it-all rifle due to limitations in long-range ballistics, ammunition cost, and weight compared to 5.56mm. The review highlights practical testing of accuracy, recoil, and maneuverability with a SIG MCX Virtus build.
