I have a Tikka 300WSM the stainless/laminated stock version. Bolt is smooth as silk and the rifle is solid. Only about 50 rounds through it, but with the right load it's one hole at 100.
I am considering getting another if I can get one chambered in 6.5x55.
I'm running about 2700fps, which is down from the 2900 published for factory loads, but I have a funny feeling that the deer or elk in the 300or so yard range I'll be shooting will never know the difference and my brass will last a lot longer not loading it hot.
