Steel Hardness

Dwight,
* As you may remember, a post on "K Date Luger Hardness" ran 2/17-2/25/03. Thor (Member #3) started the thread which offered some values for the receiver and the frame components. Agreed, it didn't mention barrel hardness. Seems the barrel's shoulder O.D. can be sometimes larger than the receiver's resulting in a deeper line on the barrel to get a line to show on the receiver. May just look like the barrel's softer.

Weissen,
* FWIW: The barrel chamber has to withstand the same pressure as the receiver and breech block. Hence the proof mark on each of these 3 components. I'd guess the barrel would be as hard as the receiver IMO. Been wrong before...maybe that's why we don't see the number of hardness dimples on the barrel O.D. like we do the rcvr./breech link....not to mention appearance considerations.
Respectfully,
WR
