The .300 Whisper (or .300 Blackout in its virtually identical, SAAMI-approved guise), is a superb cartridge for hunting deer-size game and feral hogs within 200 yds., as well as for personal protection. Minimal perceived recoil and modest muzzle rise prevents flinching and enables rapid follow-up shots, respectively.
