Drover: I can only add this to your observation.
A few years ago I bought a Tikka T-3 in 338 Federal caliber.
I added a Zeiss 3x9 scope and bought some factory ammo to get brass for my reloading.
The factory ammo shot so well I just bought two more boxes of it and have been Hunting Spring Bear with it ever since.
This is the only Tikka I have ever owned but have seen others shoot at the range and I tend to agree with your contention - Tikka's shoot well.
Hold into the wind
