I was looking at that subsonic bullet design shown on Corbin's site (http://www.corbins.com/subsonic.htm) and got to thinking... why wouldn't a larger version of that copper plated segmented bullet CCI uses in their new .22LR subsonic round work even better?
It would be easy to create the core if you had swaging equipment. Corbins sells an X-punch for doing exactly that. It's shown here in the other Corbin brother's book on page 5: http://rceco.com/img/RSBook3.PDF Plating the bullets looks relatively straight forward a kit Caswell Platting sells. They actually have an application note on plating lead bullets: http://support.caswellplating.com/index.php?_m=downloads&_a=downloadfile&downloaditemid=8
I don't see why a larger version of that segmented bullet wouldn't also work in subsonic centerfire rounds.
