Inductance of a coil

I need to build a coil with these specs: 1 inch length, .5 inch diameter, ferrite core, 30 turns of 22awg wire and 3 layers.

Can anyone give me a pretty accurate measure of the inductance of that coil? This is for a capacitor charging circuit, and I've done a few calculations of my own but I figured I'd come to you guys for a little help to make sure I've got it right. I ended up with a value of 32.99mH, (.03299H) but that seems FAR too big to be accurate.

Anyone with a more accurate calculation please fill me in  :)

Thanks again guys.
