I read somewhere that melting a blob of solder on the receiver would
anneal the case enough for drilling and tapping. I haven't tried it.
Case-hardened scrap hydraulic cylinder rod cuts well enough with
carbide.

Case-hardened '30 actions

That's '03 actions, plain carbon and case-hardened. You can tell by the

can also be spot-annealed with a cut-off nail in a
drill press. You just use friction to get a small spot very hot.

As an earlier poster says, this is not something one would do today with a
