Good point!
I agree, never lubed the neck & shoulder in 30 years of reloading and don't plan to start now. That would only add to the problem. I don't even lube the inside of the neck. If you clean you brass real good particularly the inside of the case neck there is no need to lube. Your best bet is to FL size for the first firing and then use a neck sizer die until the brass starts to fit the chamber a little too snug, than FL size again. You'll get much longer life out of your brass that way.
That is as long as your not running your loads too hot in that 7mm!
