I was thinking about a way to make a .30 carbine "rifle" more effective, and thought.... 'What if you necked down a .30 carbine case to accept a .223 bullet and used a powder appropriate for the M1 Carbine barrel length to achieve more than the 1900fps of the .30 cal. and still use the same action and mags, just a new barrel of course. Has it, could it, would it be worth the trouble?
