A friend has both and a sako in 300wsm and all three shoot very well after finding the right load,don't remember the load but he shoots the 180 sst's in all three.He said the remington was somewhat harder to find the right load for.He says the tikka shoots a little better than the sako also.We shot all three last friday and to me they all shot about the same.
I did have one in a browning with the boss on it and it would really shoot too.
