The Sauer 101 is a fine rifle as is the Sauer 100 - The 101 has the barrel friction fitted to the receiver (using heat) whereas the S100 has the barrel tenon threaded and screws into the receiver in the normal manner .
Personally the new Sauer S100 stainless with the normal polymer stock (not the soft touch version) would be my pick.
Accuracy wise - both models are accurate - just find a factory load it likes or if you handled, tailor a load to it and get out there.
