Can all types of projectiles have explosive fillers or fuzing?

Not all types of projectiles can have explosive fillers or fuzing. While many military projectiles, such as artillery shells and grenades, are designed to contain explosives, others like non-explosive training rounds or certain types of recreational projectiles may not. The design and purpose of the projectile dictate whether it can safely incorporate explosives or fuzing mechanisms. Additionally, safety regulations and intended use also play a critical role in determining the use of explosive fillers.
