I am shooting a VX3 3.5-10 on a 30-378 and really like the set up I am shooting. However I have noticed that I am having a harder time when target shooting to 500 yards because of the magnification. I know many people hear use the 4.5-14 or should a guy just step up to the higher powers. Can higher magnification be a disadvantage to a guy? Just looking for some opinions on the subject.
