Crossbow Expert is required to bypass the loading property, but you still have to abide by the Ammunition property! They're separate.
Not with the Artificer's Repeating Shot Infusion:
Repeating Shot
Item: A simple or martial weapon with the ammunition property (requires attunement)
This magic weapon grants a +1 bonus to attack and damage rolls made with it when it’s used to make a ranged attack, and it ignores the loading property if it has it.
If you load no ammunition in the weapon, it produces its own, automatically creating one piece of magic ammunition when you make a ranged attack with it. The ammunition created by the weapon vanishes the instant after it hits or misses a target. Ah! If that's what you were saying Lukas, then my mistake. I've played in like one game with an artificer so am not that familiar with their abilities.
Alright, so an artificer-infused hand crossbow allows dual wielding RAW or you can have 100 pre-loaded crossbows on you.... or just use a single hand crossbow.
