Going to sight in my 7600 270win soon. Using 130g Federal Fusion (or 130 CoreLok). The area that I will be hunting rarely gives an opportunity for shots over 150yds, and more often than not, would be shooting between 50 and 100 yards. Question being, should I zero at 50yds? Looking at ballistic charts for my load, looks like a 50yd zero is also on at 150yds and only about ½" high at 100yds.
