Hello, all. Recently I've been contemplating picking up an older 700 in .308 and switching it to .260 remington. This seems like it would require only a barrel change, but I only have one 700, that I inherited from my dad, and haven't done any work on that nor will I. Could the community enlighten me on any problems I might face doing such a conversion, and if the end result would be a good platform to shoot in the 400 to 600 yard range. Thanks in advance
