I remember a 700 in 223 with the triangle barrel. It shot poorly. I did MD's shim trick, stacked them DEEP, actually had to go buy some longer action screws. The POA shifted eight inches down, and groups went from 2 inches with a tailwind to 3/4 just like THAT. Then the chase began, I ended up needing to build a clamping jig so I could heat and bend the stock. It was not a pleasant exercise and, while a success, I will NEVER try that again. Lesson learned.
