I recently ran across a carbine built on an XP action (one of the old ones, not a repeater). Neat little rifle, but not a cartridge I'd shoot much. Can these be successfully re-barreled using the headspace-nut setup as on a Savage? I think it would make a nifty cast-bullet target rifle, with the potential to swap in a barrel in .221 for varminting.
Thanks,
Jim
