another cartridge for a suitable conversion is the 10mm, neck that down to 30 cal and you might have something... shorter case, but wider base diameter... the 224 boz for example (10mm necked down to .223) has around 900ft/lbs of energy at the muzzle... with the right powder, and a longer barrel you could possibly see 1200ft/lbs plus
