If your goal is to neck size only and you wish to keep working of the brass to a minimum, I would recommend a forester or redding bushing die.
I have a forester for my 270 win. Its a little tricky finding the right bushing, but once you do it's nice. I just dip the brass in imperial graphite media and go to town. Sure beats lubing the whole case.
I have shot a particular lot of brass 8 times and haven't had to trim the cases yet. I have found that this particular die is very easy on brass.
