hm... with 40 being max.. I'd say probably around 15 then. because it's literally just a simple belt around his hips that holds ammo, it isn't a full on ammo belt that wraps around multiple times, so he doesn't carry as much as a normal magic gun user. (not to mention got to make it so he will possible run out before a fight can be over so he can use his hammer lol)
