.338 Whisper is a wildcat cartridge in the Whisper family, a group of cartridges developed in the early 1990s by J.D. Jones of SSK Industries. Unlike the smaller caliber cartridges in the Whisper family, loads for the .338 Whisper are mainly limited to subsonic velocities.

There are two versions of the .338 Whisper:

The original .338 Whisper is based on the 7mm BR Remington case, necked up to take a .338" bullet. As the 7mm Bench Rest and .308 Winchester cases share the same case head dimensions, conversion to .338 Whisper from a rifle previously chambered in .308 Winchester is a relatively simple task.

The second version is based on the .221 Remington Fireball case, simplifying conversion of firearms chambered in 5.56×45mm or its commercial counterpart, .223 Remington.

Browse today for incredible prices & great selection of plinking, defense & target ammo in box, case or bulk ammo quantity.
