Paul, I really don't think you need to wind your own. For example,
a Coilcraft 1008CS 180nH part is rated at 620mA rms:

The "trick" is that the dissipation is a function of the series
resistance, which is very low (0.77 ohms) as long as the core
doesn't saturate.
If you want to get really silly, their "Spring" inductors are rated
at 3A rms.
Thanks, Ian, but it only took about 15 seconds to wind the coil
according to Win's spec and more importantly, winding my own enables
me to take a tap off it, which I believe may be necessary in this app.
