Sub-X (Subsonic - expanding) bullets are engineered to achieve significant impact without producing excessive noise. These bullets are specifically designed for deep penetration while operating below the speed of sound and feature a lead core. The long grooves in the gilding metal jacket, combined with a flat profile and the patented flex tip insert within the bullet's hollow-point cavity, ensure reliable expansion at low velocities. Additionally, cannelures facilitate a secure case crimp, making Sub-X bullets ideal for use in semiautomatic firearms.

• The patented Flex Tip technology facilitates expansion at subsonic velocities, specifically at speeds as low as 900 feet per second (fps)
• Verified efficacy - complies with FBI standards for terminal ballistic testing protocols, ensuring optimal performance and reliability
• Optimized case crimp - the lead core bullet, featuring a cannelured jacket, ensures a secure and reliable case crimp, enhancing performance in semiautomatic firearms
• Versatile firearm compatibility - engineered for optimal fit, feeding and functionality across diverse firearm platforms, including those with gas-operated systems
