I get it. Trust me wer'e good here.Yes, tree felling is an exacting art!
I was just insinuating the sort of finish you would get if you inletted with a chainsaw.

A business associate knows the guys over at Bailey Gun Manufacturing on the West side of Houston. They do great hot tank bluing.Really turned out nice Jackie!
He was disappointed in that the action would not blue as deep as the barrel and floor plate.
I am surprised that more manufacturers do not use 8620. While it does not possess the deep Hardenning characteristics of typical 4140 or the precipitation Hardenning stainless steels, it can be carburized to a much higher RC hardness to prevent lug galling and wear, while still maintaining good core ductility.Your project looks great! Well done!
This doesn't surprise me as I've seen plenty of Mauser actions which probably were manufactured using somewhat different alloys.
When we made Mauser M98 actions, we used 8620 and sent them off to be hardened. Occasionally we would see an action which didn't give us that deep blue we always hoped for. Just a different batch of 8620, that's all.
Super job!

And, 8620 color case hardens very nicely!I am surprised that more manufacturers do not use 8620.

I have always suspected that McMillan used something similar to 8620. Some years back, I bought one of the Bruno actions, which were made by McMilan. I converted it to a screw in shroud, and the bolt had a very hard case hardenned surface. But once I broke through that, it machined quite easily.
