I won a Christensen Arms Extreme II in 300 RUM last weekend. What are your thoughts on that caliber for Deer and Elk. I currently hunt with a Kimber in 300WSM.

I am also debating what scope to pair it up with. I have Leupolds on my current guns but have been thinking about a Swarovski. Others have suggested a Huskemaw or Nightforce. Experiences or thoughts on these?
