Bingo. Much as I like my Hornet, a .223 is way easier to feed, with tons of cheap military brass and barrel twist that will support more cast bullet designs than the typical Hornet barrel.
Also, instead of cast, consider buying blems and closeout bullets. Unless you have molds, furnace, and lead in hand, the cost and time involved may make jacketed pretty competitive. I've bought a bunch lately for about .12 a pop or so and could probably do better if I tried. Speer makes a 46gr flat point for the .218 Bee that should thump small game pretty well even without expanding.
