You can definitely get there, but there's some things to watch out for..
Coils built in this manner couple easily to external circuits, and nearby
components will affect their inductance. A conventional inductor (toko,
from digikey) is way more predictable, if not lower cost.
You can get to larger values too, just clamp an RM-4 core around it,
through cutouts in the PCB.
