.270 WIN
So I tore it apart and got to sanding. I used 1k up to 3k grit and pretty much every piece that comes apart. Every piece, bolt, bolt slide, elevator, action bars, and everything that is inside the trigger assy (sear, etc.)
With out the DIY job and Mcarbo springs the trigger pull weight was around 5 lbs. After the DIY polish it was down to a little over 3 lbs.
The action is now “expensive gun” smooth or smoother. The biggest places to look at are the action bars and the elevator. If your gun is well used you’ll see some rub marks on the inside of the elevator where it rubs the bolt. Smooth that down. Do anything that feels rough and or you can tell has been rubbing.
