Cannelure refers to a groove or groove-like feature, often seen on the surface of bullets or casings in firearms and ammunition. These grooves are typically applied to the bullet to serve specific purposes, such as: 1. **Crimping**: The cannelure allows for a crimping process to hold the bullet securely in place within the cartridge case. This helps prevent movement of the bullet under recoil or during handling and ensures consistent performance.
