My LRS2 in .308 ate over 500 hand loads and a few hundred factory loads without any issues at all. Accuracy was outstanding, I mainly shot a 168gr SMK or Amax over 44gr Varget. Brass used was Winchester, Lapua and Hornady. Primers didn't seem to matter.

I my view, the main drawback to the Blaser rifles is that you are stuck with factory barrels. They might do better if they opened up their design to custom barrel makers.
