I had the same rifle in 300 Winchester Magnum, talk about "kicks like a mule"!
I think the synthetic stocks are too light and really makes these rifles pack a punch. I was going to add some weight to the butt stock but ended up selling it first.
I believe the "Great rifle out of the box" was meaning the rifle itself is accurate out of the box. It is common to have to adjust any scope when sighting in the gun.
I have filled hollow buttstock with play sand before - makes HUGE difference in recoil and handling at the cost of a bit of weight.
