I was originally looking at a rem 700 in 308 but after trying a browning i quickly changed my mind, i got the A bolt tactical varmint heavy barrel with the bell and carlson stock, straight out the box it was sub moa at 100.
but getting back on track the A bolt is apparently the underdog of the X bolt so i would say if a A bolt can deliver that then X bolt would be a good choice. just my opinion though,
