I've had an X Bolt for a little while, holy cow is it a freaking shooter. Loves the 140 ELDM (6.5 Creed). The 1:7 twist is a bonus too, along with the longer barrel. It's a now discontinued Western Hunter model. They just barely discontinued it, you can find it for like $700-ish now.
That being said, it sits ever since I got the Tikka. Not for any particular reason other than the fact that there's effectively zero aftermarket support for the X Bolt. Lots of gunsmiths won't touch them for any major work, like a re-barrel, for fear of tweaking the action. The Tikka is better made overall and has significantly more/better aftermarket support.
Pick up a Tikka T3X upgraded model from your favorite big box store on a sale for about $1k, throw in a good scope, and you've got a lifetime rifle that will never hold you back.
