Is there any way to be sure that your players aren't tracking ammunition usage? After all, it's not normally a DM's job to track it anyway so they might not even tell you if they were doing it.
If they are, the 7th level ability could be attractive to someone without you realizing it.
The players know that ammunition tracking is not an issue at my table. I have told them that if a situation comes up where tracking ammunition, rations, etc will be required (such as being shipwrecked), I will alert them to it.
