I have a Christiansen Arms with a Remington titanium action, a titanium muzzle break, a carbon fiber stock that is chambered in the 300 WSM. It kicks like a 243, but it will make your ears ring. It is 6.5 pounds scoped, and shoots 0.6" groups, even with factory ammo. I've had it since 2005 or 2006. It is all my wife and I hunt with. She has shot an elk, 3 antelope, a mule deer, and a bighorn with it in the last 3 years.
I would fall into the group BB mentioned. I like it so much it's creepy. There's a reason the company has grown as much as it has.
I killed the ram in my avatar with in in 2009 on a solo backpack hunt in Wyoming.
