I have an X-Bolt Medallion micro in .243win and i guess ive had it 2yrs. Ive only took it to the range twice and fired a total of 25-30 rounds so i dont have a ton of experience with it. I do know from the 1st shots out of the box, cleaning between each shot mind you, its grouped well. Most of the groups were 1/2"-3/4"(most around 3/4") with one ammo shooting a little over an inch. Should only get better as the barrel breaks in.
Its a pretty rifle, made well, and handles great. Nice and light, so the fact that it shoots so well to boot is why i let it live in the safe even though i dont ever use it. Like others have said the action is smooth as silk just like Brownings always are. The trigger, although it has a terrific break, "like a glass rod", was really heavy. I adjusted it down, actually took the screw all the way out and for some reason was still a little over 5lbs. So i took it down and did a trigger job on it. Right now its around 2.5lbs-2.75lbs and will probably wear down a bit more when i use it, and still has that solid break.
Id recommend it for sure.
