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...
