Sorry, we're no custom shop. We won't chamber in Wildcat calibers. Also, we do not offer a bolt face for 223 Rem for the moment as we do not chamber in this caliber.
However this year all the Cadex actions (except the Kraken Multi-Cal) are available separately so you can get your gunsmith to chamber in any caliber group using a 308/300/338/375/408/50 bolt face.
I hope that it answers your questions.
