The Whisper family was developed as a line of accurate, multi-purpose cartridges using relatively heavy rifle bullets for a given caliber in subsonic loads. [1] [2] [3] The intention was to create an extremely accurate cartridge family for military, police, competition and specialized hunting markets that could also be easily sound suppressed.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
Subsonic ammunition is ammunition designed to operate at velocities below the speed of sound (Mach 1), which at standard conditions is 340.29 m/s (1,116.4 ft/s). This avoids the supersonic shockwave or "crack" of a supersonic bullet, which, particularly for suppressed firearms, influences the loudness of the shot.
Source(s): Nosler Load Data, [1] Hodgedon Reloading Data Center [2] The .338 Federal is a rifle cartridge based on the .308 Winchester case necked up to .33 caliber . It was created by Federal Cartridge and Sako in 2006 and intended as a big-game cartridge with reasonable recoil for lightweight rifles.
The DSR-1 Subsonic is a variant optimized for 7.62×51mm NATO/.308 Winchester subsonic ammunition usage. The barrel length is reduced to 310 mm. The barrel length is reduced to 310 mm. The 8 inch twist rate of the barrel is especially adapted to stabilize the long heavy projectiles used in subsonic ammunition.
The .308 Winchester has a 3.64 mL (56 gr H 2 O) cartridge case capacity. [9] The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns alike, under extreme conditions. .308 Winchester maximum C.I.P. cartridge dimensions. All dimensions in millimeters (mm) and inches.
7.62mm Thumper is a barrel specification optimized to run larger bullets out of standard 7.62×39mm cases. [1] Barrels are cut to a standard 7.62×39mm "Russian" chamber but the bore ideally uses a faster 1:8" rifling twist rate in order to stabilize bullets heavier than 200gr at subsonic speeds. [2]
Hodgdon. BL-C (Lot 2) for full-charge loads in the .308 Winchester and .223 Remington [14] was newly manufactured by Olin in 1961 with 10 percent nitroglycerin, 10 percent diphenylamine stabilizer, and 5.75 percent dibutyl phthalate deterrent, but without the flash suppressant used in the surplus military propellant.
