I have a savage .270 bought new in 1991 that won't hold a group anymore & did lil reading on here about converting to a. 280AI. I liked the idea, question is..Is my old savage action worth working with? Could the action be trued aswell or close anyway like a 700 to give me sub moa @ 100? Would actually like to get .5" or better @ 100 if doing this putting money into a Hart or Krieger barrel. Any thoughts & experience needed? Thanks in advance!
