Had a friends factory 7mm rem mag that the bolt would close hard on once fired federal brass only. Hornady and remington brass resized in the exact same setup and at the same time all chambered fine. All brass was fired in the same rifle too.
I own a CA Mesa in 6.5 PRC that is 1/2 MOA. Love the rifle. I have a Leupold 4-16 VX5 on top that I really like as a set up. My son has the same rifle in a 6.5 creedmore that shoots better than he can @ 3/4 MOA. I have shot mine to 700 and will shooting out to 1250 when the weather allows the range to open. Mine shoots factory Hornady ELD-X and Match well. I have found that mine likes 156 Bergers with RL26 Powder that produces the 1/2" MOA. I had a ranger .22 that was terrible and customer service is poor. The ranger is better used for a fence post......
If you get to Minnesota this spring, South of Perham MN has a range to 1250 if you would like to shoot one (assuming you can find ammo). I would be willing to meet you and let you shoot it. Currently ammoseek is showing upwards of $150 a box for factory 6.5 PRC. OUCH!
I have a CA ridgeline titanium 6.5prc, also have a 7mm08 mesa. Both seem to perform as advertised for me, haven't had any issues with them. With that said, haven't shot more than a couple boxes through both of them as yet. Have only shot hornady factory loads through the PRC, shot a couple different brands through the other, all factory, all shot well. I wouldn't be afraid to buy another one.
I have no experience, but I would be nervous buying one with some of the reviews I've come across, with some regularity. A big part of those complains had to do with shitty customer service. Not necessarily unfixable problems. But with what you spend, its disappointing the rate of issues that need addressing and then having bad customer service would piss a guy off even more.
