New wildcat?

[Don357]

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?

Hate it when that happens. And it happens to me often. Lol

If your wildcat is based on a case that's been around for more than 15 minutes someone else has already beaten you to it.

Lol took the words out of my mouth.


The wildcat idea is a notion that's ship has sailed years ago. Not only is it impossible to come up with something genuinely new but it's increasingly difficult to find a niche for a wildcat not adequately serviced by probably half a dozen commercially available cartridges.

It's been done already and not trying to sound critical but what would this round have in advantage to the .223 except for make it able to shoot from a .30 carbine?
