One thing that you might check is how the barrel lies in the forearm. When the 700 first came out the fit of the barrel and forearm was great... like they were built for each other. Later as the 700 was reaching the end of its' run the fit was less spectacular and with the heating of the barrel - it could move your POI, not with a 1 1/2" group at a 100 you need to worry about it.
