Cannon Questions - Steinhardt's Guide to the Eldritch Hunt

Considering options for Cannon builds.

Do you all think that your familiar or another minion (hireling, sidekick, etc...) could reload your character's cannon after it was fired on your turn?

"Artillery. You must use Strength instead of Dexterity for the Firearm save DC and the attack and damage rolls of this weapon. Such a weapon can be fired once before it must be reloaded with an action."

The Artillery property just says it must be reloaded with an action (not "Your" action).

To some extent my question is informed by normal DND cannons allowing multiple creatures to work together to load, aim, and fire the cannon.

Generally speaking it seems very difficult to get 2x attacks per round with the Cannon (obviously by design).

Once you have at least 3x attacks and have the Cannoneer feat (and are over Level 11) you can do 2x Cannon attacks w/ Bonus action load and 3rd attack load.

However, if a familiar can load it you can get there sooner.
