Alternatively, specialized firearms and ammunition may be used to optimize total subsonic ammunition effectiveness. These are designed from the start as dedicated subsonic projectile systems. Some examples include .300 Whisper, 300 AAC Blackout, .338 Whisper, 8.6mm Blackout, 9×39mm, 12.7×55mm STs-130, .500 Whisper, and .510 Whisper.
All controls are ambidextrous, and major components are modular, allowing for rifles to be configured in the field as needed. [2] The Heckler & Koch HK437 chambered in .300 Blackout and features a 7- and 9- inch barrel was originally announced along with the HK433 in 2017. In late 2022, the Ministry of the Interior, Municipal Affairs, Housing ...
The larger diameter, shorter 6 mm cartridge is optimized for these shorter barrel lengths, and would perform less efficiently from rifle-length barrels. The round's muzzle energy is 831 ft⋅lbf (1,127 J) versus 792 ft⋅lbf (1,074 J) for a 5.56 mm bullet, again from the same 10" standard barrel.
