I have a Mesa in 6.5 PRC. I have only shot it to sight it in. I loaded up my first handloads to shoot last weekend, but got rained out. My 3 shot sight in group with factory ammo was about MOA. The LOP feels a little short to me, though in spec, it should be right on the money. It does have a thin wrist, so that may contribute to the feeling. I think I am going to end up being very happy with it.
