I received the gun and mounted a Vortex Razor HD LHT 3-15X42 with Talley Rings. I was looking for an ultralight gun for backpack trips for elk, deer and bears. I ordered an RCBS die set and purchased three boxes of Hornady Precision Hunter 175 gn ELD-X for the break-in while waiting for my reloading supplies.
With this set-up the gun has less recoil than my 30-06 or 300 WM. The titanium side baffle break works very well, but ear protection is a MUST. The side shock will blow ammo boxes off the shooting bench, people should stand behind and not next to the shooter. I am planning to order a Scythe Ti can when they are back in stock.
After the 50 round break-in procedure my MOA was >2" and I had some signs of pressure with the factory ammunition (this has been reported by others). I emailed Christensen Arms they immediately replied and provided a Return Authorization Number and a paid shipping label. I shipped the gun to CA. The gun was at CA for only 2 weeks and I picked it up from my FFL dealer today. They did the following: Re-Barreled Rifle, Checked Headspace, Test Fired for Function, Function Test Passed, Test Fired for Accuracy, Rifle Meets Accuracy Guarantee (with Hornady Precision Hunter 175gr ELD-X), cleaned rifle and returned. They also provided a printout of the test fire report (two groups of 3 rounds, <0.5 MOA) with image of the target, velocity, etc. I do not know what scope they used to test fire (my scope was removed before shipping).
I read all of the reports on-line with people having pressure and accuracy issues with CA rifles and considered other options. Everyone I know who owns a CA rifle has never had an issue so I decided to move forward, fully aware there was a chance I could get a bad barrel.
While I am not happy that I had to return a new rifle (after spending the time and $$ to break in the barrel), I am very happy with the CA Customer Service. I have all of my supplies and will start handloading while I finish the break-in process. When I finish the break-in I will report back here with the results with both factory ammunition and handloads.
