Yes, it is called the "25 TCU" or " 25 Ugalde". You don't move the shoulder forward on a AI chamber so the neck will stay the same.
I neck the 204 Ruger up to .257 and it is a clone of the "257 Kimber" with no fire forming, 100gr NPT at 2800+fps but the OAL is at .240 so it doesn't fit any of the mini actions.
