Any reload qualifies.
After a successful reload from being attacked, for 2 seconds, Reload Mastery will not proc from being attacked.
- This cooldown is not mentioned in game. It's hard to determine if this limit still exists.
With this passive, cannonballs are easier to maintain.

Before Shelling Guardian was released, Reload Mastery was a passive that boosted Reload in the Guardian skill tree.
After the 02/14/2013 KR Deadly Chaser revamp, Remodel Magazine gained the same reloading effect as this passive.
