This is an old post . I could give my own rather expert opinion but I am amused to read what has already been said. Plus by now the project has already gone on.. Notice that "expert" opinions should be circumspect. As a working tool an die maker with both heat treating furnace and a Rockwell hardness testerI can tell you I have tested the hardness of every bolt and breechbolt I have ever dealt with. That is all I will say other than a few degress of Rockwell C isn't gonna screw up your rifle. Have fun.
