Barrel Bedding blocks, Why not SS

Almost all of the barrel bedding blocks I have seen (which is not many) have been made out of aluminum, Why not make them out of Stainless Steel so heat expansion is the same?

    robbar, Are you talking about the bedding blocks that go under the reciever and run the entire length of the forend, ala HS Precision? That aluminum block is made from CNC'd Aircraft grade aluminum, and would have to get pretty hot before you'd have to worry about heat expansion, they're all freefloated stocks anyway with a layer of fiberglass cloth, Kevlar and whatnot over it. What is your worry with , anyway? [img]images/icons/confused.gif[/img] Jay

    Robbor weight comes into play and the fact that aluminum radiates heat better than stainless. I believe the idea is to transfer the heat out of the stainless. It would be the same idea as a steel sleeve inside an aluminum block in a car engine.

    Easier to machine and lighter. As to expansion, you are going to need a lot of heat to expand either SS or Alum. I doubt most of us shoot that agressively.

    Besides, you have a skim coat of epoxy bedding between the two don't you????

    I was talking about The barrel bedding blocks used in LONG Range , long barrel guns that clamp the barrel to increase stiffness. I already got a good answer via email, but thanks anyway.

    My block you glue the barrel in to the block. What did the email say about the material used for the block?

    I use regular 34CD4 ( US 4140 steel ) with a electroless nickel platting or hard chrome on to avoid rust , barrels are glue with Loctite in , Stainlees is more difficult to machine and except for the look you win nothing

    good shooting
