Does anyone know the max OAL for a cartridge using a Winchester M70 SA? There are some cheap M70 Ultimate Shadow rifles with CRF actions and I figure I might use one for a build. New barrel and stock and it should be good to go. Just don't know if I need to go LA or if I can use a SA. Thinking x57 case of some type. Maybe 257 Bob, maybe 7x57.
