i bought a Christensen Summit, Approx $6,000 and when I got it the bolt slid VERY rough. i had 4 weeks before my first ever elk hunt. I sent it back to Christensen and after 2 weeks they sent it back and its no better. it has remained in my gun room now for a year. The rifle fires fine but if I go to load the next round the bolt is still very rough, catching so I cannot go quick with any confidence. Any suggestions? the service guy at Christensen was brutal...maybe he is gone now? Shame to not use it. I ended up buying a Tika which worked fantastic right out of the box
