Never been on here before, but I have some input.
I own both.. The X-bolt is a Medallion in .300wsm and the Ruger is a MKII Ultralight in .270win.
Both are great guns, they are two different actions that essentially accomplish the same thing. I think it all depends on your preferences in a rifle. Do you prefer a hinged floorplate or a box mag? Controlled or push feed? Tang safety or M70 type? The browning has a wonderful trigger, better recoil pad and the slickest magazine system I have ever used... but I have cursed it when I forgot magazines at home!! The Ruger has a better safedy, scope mounting system and I prefer the CRF type action. I understand the Hawkeye's LC6 trigger is an improvement over the MKII, but I have not tried one.
My X-Bolt is a tad more accurate, but the Ruger has a real light contour 20" barrel which I'm sure doesn't help with 5-shot groups.
It's always a toss up between the two when I go out hunting, unless the wife comes, then she gets the Ruger
Hope that helps... You really can't go wrong.
