The cartridge is derived from the 0.221 Remington and is necked up to accept a 0.308 (7.62 mm) bullet. The 0.300 Whisper was designed by J D Jones of SSK Industries for firing extremely heavy, accurate, ballistically efficient bullets at subsonic velocities. The cartridge was subsequently adopted for use in suppressed weapons by a number of US special operations organisations and is in use by special operations units worldwide. The case is rimless, bottlenecked, Boxer primed and loaded with relatively heavy
bullets which range in weight from 8.1 g to 15.5 g in standard loadings. Although expressly designed for use with suppressed weapons, use of the 0.300 Whisper is spreading to non-suppressed firearms, as it generates no sonic 'boom' upon leaving the muzzle in its subsonic loadings and in this version, the bullet delivers more energy on target at 200 m than any western subsonic round, save for other 'Whisper' cartridges. Unsuppressed, the subsonic version has less noise at the muzzle than a standard 9 × 19 mm ball round. Applications include selected compact assault rifles. Most rifles chambered for this cartridge are adopted from AR-15 or M-16 rifles.
