It has been a while ago that I read about people converting the 17 HMR rimfire to either the 17 Mach IV or 17 Ackley Hornet. The barrel being changed from the rimfire reciever to a centerfire reciever. Is this sparking anyones memory? If I remember right there is a smith over in Oregon that does the chambering and reworks the extractor. Any information would be great.
