From my calculations 30g wire 2mm with 10 wraps you will get 2.2Ohms
same setup 3mm 7 wraps to get 2.2 Ohms
3 mm 8 wraps will get you 2.4 ohms
2 mm 11 wraps will get you 2.4 Ohms
I know its springy, but here is how I deal with it. I wrap it which ever way, insert it, heat it up, clamp it, pull out with inserted screwdriver so it wraps more tightly, then repeat above steps to get perfect coil. If while pulling on the coil the leads become longer I readjust. Hope this helps.
