This passive affects anything that uses ammo such as combos, Actives, and Special Actives.
- When the reload triggers, you'll hear a reloading sound as you consume the cannonball.
Even though the description says it "reloads" at the use of ammo, Remodel Magazine will not work alongside it, so you can't gain extra cannonballs.
Even if you use more than one cannonball at once (such as Shooting Star or Quantum Ballista), you'll only reload one cannonball.

Gas Piston System's skill icon uses the design of Shelling Guardian/Tactical Trooper's cannonballs, despite Deadly Chaser having no interaction with Echo.
