Dear Sirs
I have been reading about making rifle barrels but I haven't found nothing about their heat treatment.
Lots of texts and sites talk about using C4140 steel for the barrel and the tools and operations required to produce them, but doesn't say if final heat treatment is necessary.
A C4140 steel rifle barrel needs to be heat treated ?
If it needs, what is the correct procedure ?
It is heat treated only at the chamber or is completely heat treated ?
Thank You Very Much in advance for any information you can provide about this subject.
