I have a few Vixens here and I would think there would be a market for such guns today.

The Magnum is a touch too long for modern tipped stuff to magazine feed or to get close to the lands, but every 222 Magnum actioned Vixen I've come across has shot lights out as long as the lands were within an inch.

I've ran a few 223 Vixens but none have ever shot as well as the 222 or 222 Magnums, except an early Bofors barreled one.
