Does anyone know what the average rockwell hardness of a gun barrel is? Does it vary significantly by maker?

Seems like it's about Rc 45-50 or so.

Barsto pistol barrels are R-C 38-43.
I don't see anything about rifle barrel hardness in Brownell's.

It depends on whether the barrel is more or less partially covered by the slide. Just ask TwoBlink. He says that since a Beretta slide is an open design, the barrel is susceptible to "denting".

I suppose that means that every rifle or shotgun ever made has the same dangerous problem, but you'd have to talk to twoblink to confirm....

:rolleyes:

on a pistol, somewhere between 35 and 45 Rc.

You don't want the barrel to be too hard, or it will fragment instead of bulging in a overpressure condition. A hand grenading gun will ruin your day.
