I can speak to the varmint version but I bought a Tikka T3X Roughtech Ember 3 months ago and could not be happier with it. The build quality is obvious when you handle one. Love the fluted bolt. Trigger adjustment is a snap an mine shoots fantastic. They seem to be particularly long throated but mine doesn't seem to be too sensitive to seating depth. Go for it!
I don't have the varmint but I have several t3 lites, there by far my favorite factory rifle. There butter smooth and dead accurate. I would buy with confidence.
It's a Tikka, odds are it should shoot very well. I have a CTR 223 and it's boringly accurate. My only gripe is the throat is a little short on the 223.
