As most have said above, it depends on how much you shoot and how much you plan to shoot in the future and in addition to that.. how pessimistic you feel about ammo availability.
all the above has to do with the 'sport' of shooting... if a bad thing happens and you would actually need hundreds of rounds of ammo for defense... it really doesn't matter how much you have on hand... there will be plenty laying around for the taking.
