I have a Winchester 770 that started out as a 30-06. I have been kicking the idea around of making it into something different. I was thinking new barrel, stock and trigger. What cartridges do you guys suggest? I reload so doesn't need to be something that is found in every store so to say. I thought I read somewhere that the 6.5 Weatherby RPM uses the same bolt face. Any and all suggestions are welcome. Thanks.
