Sure, sending it to Bugholes for action truing and setting it up for a prefit, shouldered or nut style can be done and their work is amazing. Accuracy potential is roughly the same, the only advantage to the nut is the ability to fine tune the headspace. Getting a shouldered prefit barrel from a top tier manufacturer like Bugholes will likely not have a headspace problem, but random issues can pop up although unlikely. Note, you can't do a shouldered prefit for a Rem 700 without the gunsmith having it in hand. I'd consider if going the action truing/prefit route is the most cost effective for your end goals or not. You can go off the deep end pretty quickly with a Rem 700 by adding these operations: side bolt release, primary extraction/bolt timing, M16 extractor upgrade, scope base holes upgraded to 8-40, bolt fluting, large bolt knob, pinned recoil lug etc.
I've went down that road with two 700 actions (sent to Bugholes, LRI, SAC) and ended up spending tons more money to get them to the level of quality/features that a standard Zermatt Origin has out of the box for less money. I won't make that mistake again. I would sell the 700 and use those funds to buy an Origin and then buy the prefit barrel from bugholes.
