I have shot all three and own a 19 calhoon(Hornet), the the Badger is also a great round its a 30 carbine necked down to a 19. I personally dont have a use for the 19-223 but if you want a fantastic small varmint cartridge badger or the calhoon are great. they are customized cz527's he uses Pacnor barrles and does lots of little tricks to make them shoot great. Mine is a consistant 1/2" gun and if i do my part and the gods are with me, one ragged hole. If you are at all interested you owe it to your self to call Jim you will learn alot if you ask questions he has a wealth of info and he'll share it. I will probably get a badger later but for now my Calhoon is my go to varmint gun.
