I noticed upon inspection of my Remington 700 SA that the bolt lugs show some signs of galling on one of the lugs. Its at the front of the lug Just seems to be worn down round a bit. I had the gun re chambered about 200 rounds ago. I am wondering what is a cause and remedy for this? Also the one lug with the galling has more contact then the other side due to it has more bluing worn off it. thanks for the help.
