I bought a Kimber Hunter in 6.5 a few years ago when they first came out. I bore-sighted it. Loaded 3 rounds of federal fusion's and it shot 3/4" at 100yds for the first 3 shots ever.
I sold that rifle that year but have since bought 3 Montana's. A .223 Rem, a .243 Win, and a 6.5CM. The ergos on them can't be matched by a custom rifle IMO. They fit me perfect.
All of mine are the newer, threaded versions with the 100yd MOA guarantee. And all of them meet that with ease.
