300 Rifle Capacity.
In super-sonic mode, the 300 WhisperŽ essentially ballistically duplicates the 7.62. x 39 Russian round with far better and more accurate bullets than usually found in the Russians .310-.311 bullet diameter. It makes an excellent 200-250 yard deer cartridge in very lightweight rifles with very little recoil making it an excellent choice for any individual who may be sensitive to recoil. As a recreational cartridge it is accurate, has a low noise level in any mode, and with the heavier bullets is capable of 100% performance on Silhouette Ram targets. The 300 WhisperŽ utilizes the 221 Fireball case opened to 30 caliber as its parent cartridge.
SSK is currently accepting orders for bolt action rifles in several varieties, AR-15/M-16 complete guns or upper units, Contender barrels or complete guns. Reloading dies are in stock. Sound suppressors in a variety of configurations are available.
J. D. Jones is the inventor of the 300 WhisperŽ. There are other WhisperŽ cartridges at every caliber step from 22 through 50. Data on them will be released as is found appropriate. Serious inquiries regarding the 500 WhisperŽ (sub-sonic 750/1040 FPS or sonic 750/ 2000 FPS) from a lightweight repeating rifle will be answered on an individual basis.
