Twist rate should be fine. My tikka 300wsm shoots 190gr VLDH no problem & its a 1/11, Xbolt appears to be 1/10.
Does it shoot well with any other projectiles/loads to verify its not a scope/rifle issue?
I wasted a fair bit of time and components trying to get my 300wsm to shoot 200gr ELDX well, different powders, charges & seating depths. For whatever reason my rifle just wouldnt shoot them, but my old 300 win mag shot them great. Went to 178gr ELDM & it shoots those amazing, along with the 190gr VLDH.
