Of course it depends on what atty you are using but I've found that dual coils 6 wraps each @ 3 mm of 24ga/36ga (kanthal) clapton wire will give you around .3 ohms.
Personally I prefer 316L SS for my claptons in temp control mode. If I do the same build using SS instead of kanthal I end up around .17 ohms so I add a couple extra wraps to each coil to bring it up to around .2 ohms.
