I assume that Tim has a good feel for what's "hard" in 1/8" music wire.
That's the largest legitimate diameter of real music wire, and it's the
softest. Still, it's not soft. I think the ultimate tensile is around
110,000 psi or something like that; the Rc hardness would still be pretty
good, compared to any ordinary plain-carbon steel.

That sounds way low. Cold drawn 1045 rounds are nearly that strong.

261 to 288 ksi here...

Yeah, if you caught my correction, the minimum is around 220,000 psi.
