It seems to me that the work has already been done. If you want that kind of performance, get a .17 centerfire. To cobble together a rifle to handle a cartridge that hasn't proven itself is IMHOP kind of stupid. I love my 93r. If I want another .17 (which I don't) then I would probably go with the .17 hornet. It can be reloaded and just about any short action can be fitted to a barrel chambered for it. My .223 is my step up from my .17 hmr.
