First let me say that I do not have any knowledge as to what steel was used for the action body on these SKB guns. However as they were not originally case hardened there is a strong possibility they used a heat-treatable alloy steel & as such should likely NOT be case hardened. Don't have one case hardened until you find out for an Absolute Certainty the metal is compatible.
