Uchiha's dont just automatically have large reserves.

Itachi's limit with MS was 3 uses before needing to deactivate his Sharingan and rest.

Kakashi's limit with the MS when he first started was 3 uses too before he required rest and had difficulty moving.

Considering that Kakashi is already noted to have barely average chakra and that his Sharingan drains him far more than Itachi's drain him, Itachi's reserves are not at all impressive and are actually within the ballpark of Kakashi.
