Wind my own shunt?

I need some advise on building an current/voltage monitor for my 12v/70A
that powers my 300w 2m amp. I know I need a shunt arragnement to allow
less full scale on a 1ma ammeter. The problem is building the shunt
resistor. I checked
the 2006 ARRL handbook and it tells me I must wind my own shunt from
McMaster-Carr is a source for nichrome wire of various diameters
(thanks to Sandy and Dr Bruhns) but honestly, isn't there a modern way
to tackle this problem that does not involve
building a unique component from scratch?
