I plan on building one next year, however when it comes to Bergara, I have purchased two of them, one in 7mm Rem Mag and the other in 6.5 Creed both are B14 HMR. I can tell you this about the Bergara, to me they are the best built Factory rifle you can buy, the barrel is floated, the action is smooth, the trigger is good and is adjustable with no creep. As for açcuracy, the 7mag produced MOA out of the box with factory ammo and with handloads they shrunk to .5 and smaller. The 6.5 Creed is the same out of the box with factory ammo, just now starting to try load development, I am sure it will produce with no problems. I am surprised nobody responded to you on the cartridge, I would have thought more people have owned one to give you a report.
