I happened to find myself in the possession of a Ruger M77 in .243 Win that was mistreated. The M77 was given to me by a relative who tried to sand and reblue over 10 years ago. The finish has since started to lightly rust all over including inside the reciever and bolt. I can't see the rust until the rifle is in good light. Is this a loss cause or can it be saved? I want to find out if the M77 shoots well before investing anything significant. If I take her to a gunsmith can they get rid of all the rust (inside bolt) and what types of finish are recommended? Any pratical at home rust remover? All recommendations would be appreciated. Thanks.
