Pharm,
I have seen a Tikka lemon, or two. One had a tight chamber and different brands of factory ammo were REALLY hard to close the bolt on. This was a 30-06.
Another, was a mediocre shooter with various factory ammo. That was a .270 Win, and the owner sold it to buy something else.
Most recently, we have a 300 WSM in our shooting group that isn't doing so hot. No final verdict yet, as I haven't done anything with it. However, my buddy has messed with it for the owner, and it seems like 1.5 - 2" rifle. He certainly know enough about rifle setup and shooting to evaluate equipment. The scope has not been ruled out yet, though.
