I've had a tub of those coils for a few years that a seller on eBay threw in as a freebie but never got around to using them because I don't use Kanthal much - I've just fitted a pair of them and got a reading of 0.35 ohms - so yours are closer to the stated resistance than mine lol.
I think its just that particular brand of coils mate. I believe they are just cheap generic Chinese coils and they just write whatever specs they feel like on the tubs. I've tried a few different types of coils that came in that style tub - the resistance was always way off. The bulky complex wires can be close (but take forever to ramp up) but the twisted wire variants are way off
It isn't your mod or atty at fault bud - the coils work alright but are a bit meh.
If you want to buy reasonable budget coils, Coilology, Wotofo, Vandy and Geekvape are OK. Those cheap Kanthal tubs are a bit wank.
