I bought a M700 Sendero in 7mm STW for the usual reasons:
* The construction worker bought more rifle than he could afford
* It was too heavy to carry much, and still kicked hard
* Ammunition was expensive
* It was way more rifle than necessary for 140-lb whitetail deer at 150 yards
So I bought it right. ( Its inventor, Layne Simpson, is somewhat of a local boy.)
It was very accurate. As others have said, that is probably due to the long, heavy, fluted barrel, and the nice stock with a full aluminum bedding block and pillars. I found the trigger to be good very good at 4.5 lbs, but adjusted it down to 3 pounds. It was a trade item for me, and went to rancher out West who loves it for elk across the hills. But he has a horse to carry it.
