I'd think that perhaps our friend Greg T. might like to have that sectioned action, but I would not pretend to speak for him. He'll be along & can do that quite well his self;-)
As a side bar, what's the FFL transfer status on a sectioned action?

Meantime, do you have access to a Rockwell hardness tester? It would be interesting to verify your thots with a series of point tests. Please don't misconstrue my thots .. I do not question your machining observations. Rather, I think it would be interesting to know the actual hardness values on an R scale, that's all. I think it would translate better in that manner and more folks could relate to how much harder.
