What is .500 whisper?

The .500 Whisper is a wildcat cartridge designed for suppressed, subsonic use in AR-15 rifles and other platforms. It is designed by J.D. Jones of SSK Industries. Here's what you need to know:

• Purpose: Primarily intended for suppressed shooting, achieving very low noise levels while maintaining significant projectile weight and energy.
• Design: It utilizes a heavily modified .300 Whisper case, necked up to accept a .50 caliber bullet.
• Ballistics: It typically fires heavy .50 caliber bullets (often around 750 grains) at subsonic velocities (around 1050 fps). This results in significant energy transfer at close ranges, despite the relatively low velocity.
• Suppressor Use: Essential for realizing the cartridge's full potential. The large bullet and subsonic velocity minimize the sonic boom, resulting in very quiet shots when used with a properly designed suppressor.
• AR-15 Adaptation: Requires a dedicated .50 caliber barrel and a modified bolt. The cartridge is typically single-fed due to its size.
• Effective Range: Limited due to the rapid drop of the heavy, slow-moving bullet. Effective range is generally considered to be within 200 yards.
• Availability: Due to it being a wildcat cartridge, it is not commercially widespread. Reloading is often necessary, requiring specialized dies and components.
