You don't really need to go up that high in resistance. The temp control handles the power. Besides, you probably wouldn't have the room to fit a coil at 0.3-0.4 ohms. You're talking about going with somewhere around 30-40 wraps since the resistance of nickel wire is so low....or using something like 34 gauge nickel wire, which would be even harder to work at since it would be so thin and so soft. This is also why you really can't do dual coil builds with nickel wire since the resistance is dropped in half when you use dual coils rather than a single coil.
FYI, ohm meters are pretty much useless with nickel wire since the resistance of nickel wire changes as power is passed through it. For example, if I hook up my 0.1 ohm nickel coils to a multimeter, it will initially show one resistance and then about a half second later, the resistance will change to a different value.
