Here is Nosler's load data for the 7mm Rem Mag
http://www.nosler.com/nosler-load-data/7mm-remington-magnum/I have some 175's just haven't had time to work up a load but I have messed with the 168's and the 30cal 210's and found it fairly easy to get sub MOA groups. I would think the 175's should be no different.
