The smoothness of a bolt action has always been an issue that puzzles me somewhat. I have dozens of bolt rifles with a wide variety of smoothness on how the bolts function. My "crown jewel" is a customized Argentine Mauser that was beautifully machined and finished to start out with. It is really a beautiful marriage of steel parts. On the other hand, I own some Savages that are considerably rougher, and I have Rugers, Winchesters, Brownings, etc. that fall in the middle. But, so what? The roughest bolt action I have has never missed a lick when shooting as fast as I can at a moving target, and will shoot sub-moa. The Tikka T3 that I looked has synthetic inserts and as expected is very smooth and quiet. It feels "very nice". But so what? I just don't see any performance-related benefit to that. There are so many aspects to the design and function of a bolt rifle that I find more important - to me.
I am not the least bit attracted to the Tikka - although I believe that they are accurate, and everything Tikka fans proclaim them to be. I have nothing against the Tikka, just not for me as I prefer different safety system, bolt design, etc. I just think that the smooth bolt function is a wonderful answer to a non-existent problem. Yes, it does feel better. And feeling better is nice. But it's really way far down on my list of importance. Just my opinion..........
