Boulder City, Nevada Patent of the Year – 2024/2025
Jamie George McWilliam and Charles Edmond McWilliam has been awarded the 2024/2025 Patent of the Year for their innovative approach to bullet stabilization. Their invention, detailed in U.S. Patent No. 11976906, titled ‘Bullet stabilization in subsonic flight’, introduces a novel design aimed at enhancing the accuracy and reliability of subsonic ammunition.
This advanced bullet design incorporates helical fins that are formed during the loading process, either through the rifling of the barrel or by mechanical means within the casing. These fins impart additional angular momentum to the bullet, counteracting the natural loss of spin that typically occurs in subsonic flight. By maintaining consistent rotational stability, the bullet experiences reduced tumbling and improved trajectory, leading to more precise targeting.
Furthermore, the bullet features a softer, mechanically formable tail section, allowing the fins to be created without compromising the structural integrity of the projectile. This design enhances manufacturing efficiency and ensures consistent performance across different ammunition loads.
McWilliam and McWilliam’s innovation addresses long-standing challenges in subsonic ballistics, offering a practical solution that enhances the effectiveness of suppressed firearms and specialized ammunition. Their patent represents a significant advancement in firearm technology, with potential applications in both military and civilian sectors.
