300 Whisper ®

Whispers®: A wide range of calibers encompass the ‘Whisper®’ series of cartridges. A “Whisper®” cartridge must be capable of sub-sonic extreme accuracy with very heavy bullets for its caliber; i.e. 240 grains in 30, 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 300 Whisper® was the first of the series, and, contrary to what you may have read about it, the fact of the matter is the cartridge was designed as a multi-purpose cartridge from the beginning.

6.5 MPC

The 6.5 MPC (Multi Purpose Cartridge) is a SSK development urged by Brian Hormberg (USMC) based on the 5.56 cartridge shortened and opened to 6.5 MM and the same OAL as the 5.56. In the M-16-AR-15 rifles it utilizes the 5.56 bolt and magazines as well as all other parts except the barrel itself. Its design adapts it to a short Close Quarter Battle rifle with a 12” barrel moving a 107 6.5 SMK at 2400 FPS with superior full auto controllability and excellent accuracy. The 12” barrel model easily puts it into the realistic 300+ yard combat category and longer barrels stretch that realistic combat range considerably further. Read More
