A paint ball including a paint ball shell and an axis extending through the shell to define first and second poles. The paint ball shell fractures in a predetermined pattern upon the receipt of a fracturing force to form fracture lines from the point of impact circumferentially toward the first pole

A paint ball including a paint ball shell and an axis extending through the shell to define first and second poles. The paint ball shell fractures in a predetermined pattern upon the receipt of a fracturing force to form fracture lines from the point of impact circumferentially toward the first pole and from the point of impact circumferentially toward the second pole.
