Research notes
According to the SSK website, a “Whisper®” cartridge must be capable of sub-sonic extreme accuracy with very heavy bullets for its caliber. The 375 Whisper is based on the 7mm Bench Rest case together with the 338 and 416 caliber to convert 308 case head size actions to fit in AR-10 actions.
