9 and 45 (especially .45), are much more "worth it" than .223 for reloading. With plated or cast bullets that many companies sell you can get your cost per round to a quarter of what factory ammo is. The cost and time that goes into loading .223, especially for "plinking" ammo for an AR or something just isn't low enough to be worth doing in my opinion. (though with the current shortage of ammo, maybe its time I get back into it, if I can find bullets for a decent price)
