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

Here's a link that should prove helpful in explaining the whys and wherefors of glass bedding.

If the glass bedding job was done properly, you got yourself a VERY sweet deal there!

You have a fine gun at a gift of a price.
I think every gun should be bedded, and for me its a must with a wood stocks.
good luck and enjoy your bedded gun.

Quite simple. A custom gunmaker can charge big bucks to inlet a barrelled action into a piece of wood so closely that you'd think the tree grew around the metal. Factory stocks can never fit like this, but to shoot their best, most guns need to have their stocks fitted pretty closely-usually closer than the factories can afford to do and still sell their guns at a price you and I could afford! The use of a fiberglass-filled epoxy-resin compound between the wood and metal (or synthetic stock and the metal, such as yours) provides a reasonably economic way to make the stock and barrelled action fit closely.

To do this, some of the stock material is removed from the receiver recess and the barrel channel, and replaced with this epoxy resin compound while the stuff is still pliable, then it is allowed to set up hard. When done, the stock and barrelled action fit extremely closely, and are bedded in a material that's stronger than either the original wood or composition material of the stock.

This is "glass bedding". Several companies make this stuff, such as Brownell's "ACCRAGLAS" and "ACCRAGLAS GEL" I have used both of these products, and they are great!
