This video from Defiant Munitions explains the concept of 'cannelure' in firearms ammunition. Cannelures are grooves or indentations found on bullets or cartridge cases, serving various purposes such as aiding in case neck tension for proper bullet seating, preventing bullet setback during recoil in tubular magazines, and acting as a crimping point for some ammunition types. The explanation aims to demystify this often-overlooked feature for firearm enthusiasts.

This video explains the function of a cannelure, a crimp line on ammunition designed to prevent bullet setback. Bullet setback can lead to dangerous pressure spikes and malfunctions. The presence of a cannelure, like on Defiant Munitions, often signifies higher quality self-defense ammunition, as some manufacturers omit it to save costs. Understanding cannelures is crucial for reloaders and those selecting self-defense rounds.
