Re: 180 barnes tsx// New guy
They are a challenge on Rugers,but they can be done. You create a more consistent platform for the receiver and bottom metal to mount on. Metal on metal intead of metal to wood. After doing it, I got about 1 inch groups at 100 yds. If you are getting that with your gun now, I don't know if I would bother. Unless you plan to hunt Alaska with the nasty weather.
Google it, there are quite a few youtube videos out there, I watched them for hours before doing anything on mine.
Here is one from Midway. It takes longer than he shows,but givess you the idea.
