Brilliant little fox round, but here is the fly in the ointment, factory ammo is expensive, and with the exception of Hornady 35 grain vmax, is pretty crap, so unless you are happy to pay through the nose for generally poor ammo, reloading is the way forward with a hornet, and for that reason, unless you are happy reloading, I would suggest the superb .222, as there is a plethora of excellent factory ammo for it from all the major manufacturers, and you have the benefit of being able to shoot small deer too, should you wish.
