I owned one in .338 Win. Mag. once. It was a miserable shooting rifle barely closing on 2". Partitions, Accubonds, TSX's, and Scirrocos all tried nothing good.
But I have seen quite a few that shoot awesome. My favorite blaser is the K95. They are jsut neat.
I do love the swithc barrel system, and the mounts though. I may try one again some day, but for the price, I'll likely build another custom.
