I have a very nice rem 700, trued, krieger, mcmillan stock, jewel trigger etc etc. It has been a great gun for me and it is a 300 win mag. I was thinking of selling though as I have grown kinda bored with the caliber... I just want to switch to something else. I am wondering what my caliber options are if I re barrel. This is a long action obviously .... but is there also a long action magnum?? Is there a guide to rem 700 actions somewhere that sort of shows what caliber would fit in what action? Specifically I would really love to leave everything the same and just re-chamber in 6.5x284? Is this possible? Thanks
