A recently granted patent (Publication Number: US11906275B2) discloses a novel bullet design aimed at enhancing stability and performance. The bullet comprises a core with a bow-side section, a tail-side section with a base, and a guide band, all enclosed within a jacket. The core and jacket feature complementary profiling to create an anti-rotation structure, ensuring a secure fit. Additionally, the bullet jacket is designed to deform under firing pressure, further reinforcing the anti-rotation mechanism. Various embodiments detail the use of latching elements, rough surfaces, and solidification fluids to improve the interaction between the core and jacket, ultimately enhancing bullet performance.

Furthermore, the patent includes methods for securing the core to the jacket, such as friction welding, diffusion welding, or spot welding processes. The design also allows for relative axial mobility between the core and jacket while preventing rotational movement through a protrusion-recess structure. The patent covers a range of features, including the use of locking pins, bore creation for insertion, and temperature manipulation during manufacturing. Additionally, the inclusion of solidification fluids like synthetic oil or adhesive further contributes to the overall stability and performance of the bullet design. Overall, the patent presents a comprehensive approach to bullet construction, focusing on anti-rotation mechanisms and innovative methods for enhancing bullet functionality in various applications.
