US12305966 - Disruptive projectiles and method of making the same

A disruptive projectile for use with a pneumatic weapon or similar device can include a shell defining an interior volume, the shell being frangible on impact with a target. The interior volume may be provided with a flexible line that may be arranged to extend and/or expand when released from the frangible shell on impact with the target, increasing an effective impact zone on the target. The flexible line may entangle with or otherwise impede operation of a rotatable element of the target.
