I just bought a M-70 featherweight in 6.5X55 Mauser at a local auction . I got it new in box for $325.00 . I didn' t go there to buy it but it went so cheap I had to .
You could sell the Rem 788 if you want but I wouldn' t rebarrel it , You start with a $300 dollar gun and spend the money to rebarrel and still only have a $300 dollar gun .
