In shotgun terminology, what does crimp refer to?

In shotgun terminology, crimp refers specifically to the part of the shotshell that bends inward to secure the wadding or shot. This crimping process helps keep the components of the shell together, ensuring that when fired, the shot or pellets are properly contained until the shell is discharged.

Understanding this term is essential for those handling shotguns, as a properly crimped shell can affect performance, accuracy, and safety. The crimped end also plays a role in how the shot disperses when it leaves the barrel. Therefore, recognizing the function of the crimp in terms of securing the shotshell's contents is crucial for safe and effective shotgun operation.

Other options don't relate directly to this definition. The overall length of the shell refers to a complete measurement, the type of projectile used does not pertain to the structural aspect of the shell, and the gauge of the shotgun relates to the bore size rather than any specific aspect of crimping.
