I just purchased a ruger m77 markII in 7mm rem magnum.I bought the gun used from my uncle it has a after market bell and carlson synthetic stock on it and he said that it has been glass bedded.I have heard about this before but do not really know what it means and I have hunted and shot rifles and stuff all my life and did not want to sound stupid by askin him whats that but at the risk of soundin stupid anyway what is it?Anyway I gave him $450.00 for the gun and it has a leopold 3x9 x-II scope on it.I was shootin some of my handloads thru it and it is the sweetist shootin rifle I have ever shot.I cant wait to really get it tuned in with a load.Anyway can anyone tell me what the advantages of glass bedding is? Thanks
