I have not seen the Timber model. All of my bbls shoot very good. The 223 and 308 shoot under 1" at 100 yards with factory loads. The 300 WIN MAG shot under 3 " at 300 yards with 2 different factory loads, and I am developing hand loads for it now.
My 375 bbl has only shot reduced loads for whitetail deer so far, but I have no doubt it will shoot good to.
The nice thing about the Blaser is that you can add calibers from the 223 to the 416 for much less than the cost of another rifle.
I have been very happy with mine.
