The 16" bbl Blackouts do give more velocity for hunting than the short ones do. A can on the end of your rifle is going to cut down significantly on the overpressure at the shooters ear, and can bring the muzzle blast down to more manageable levels. Versus 6.8, you're not gaining anything but diameter. The supersonic and subsonic bullets draw their names from how they each respectively relate to the sound barrier. .300 Blackout is an intermediate caliber that performs with a better ballistic capability than 5.56x45mm while retaining the same round capacity using a standard M4 magazine. In the dark, maybe just up out of bed, and then theres a blinding fireball and an ear-splitting report, and its difficult to recover situational awareness, especially at my age, and even with my rail-mounted light.
