The crimp of a shotgun shell is more than just a method of sealing the shell; it’s a crucial factor that influences the shell’s performance. The folded crimp and the rolled crimp are the two main types used by manufacturers and hand loaders alike. Both have their loyalists, each claiming superior performance based on specific criteria. The decision often boils down to the shooter’s priorities, whether they’re focused on reliability, ease of reloading, or shot pattern consistency.
Folded crimps, usually star-shaped, are perhaps more common in modern factory-loaded ammunition and are frequently seen in hunting and sporting shells. On the other hand, rolled crimps have a storied history and are often associated with specialized or vintage loads. Understanding the differences between these two types can help shooters make more informed choices tailored to their particular needs and preferences.
