I can't comment on the 22-250. I have a 243 dropped into the mdt xrs.
It shoots fine, accuracy good, stock improved it which is good.
2 things about the stock though, wish that the QD sling mounts would be re-positioned in the butt (middle or bottom). The sling I use interferes with my cheek placement, so I had to use the QD mount on the other side.
First time using it in some bad weather, (misty, so rifle would get damp after all day coyote hunt) would wipe rifle down and then let dry. After 3 days of this noticed that about 1/3 of the small bolts holding the polymer to the frame have now rusted. Looks like the bluing or whatever coating they use on them has been rubbed off. They should be easy to replace.
