Will prolong use of this kill the shell, or continue to loosen?

I am thinking of just getting phil wood BB with the cups that fit 68-73mm.

Thanks for any advice.

Edit: two shops and no one has a 70mm in stock.
Rty to find just an axle intended for 70mm BB and same cups as yours. Campy ones of the right period will be marked SC-70-xx, but they come in 109 or 102, AFIK
