The Lowdown on .300 Whisper Ammo

SSK Industries created .300 Whisper ammo in the early 1990s as a cartridge that could utilize supersonic and subsonic bullet velocities. According to SSK, a Whisper cartridge "must be capable of sub-sonic extreme accuracy with very heavy bullets for its caliber, i.e. 240 grains, as well as moderate to high velocity while maintaining excellent accuracy with light bullets for the caliber, i.e. 125 at 2300 FPS in 30." The cartridge is based on the .221 Remington Fireball and has a rimless, bottleneck design. The Cartridge was designed with AR-15 and M-16 families of rifles in mind.

Other manufacturers

Although SSK Industries owns the trademark to Whisper, a number of other ammunition manufacturers offer similar cartridges under such names as .300 Warrior Carbine and .300-221, each based on the .221 Remington, as well.
