Most people tend to zero somewhere between 25 and 100 yards. This is really a matter of preference and it is often best to consider what your philosophy of use for the firearm is when you decide on a zeroing distance. For example, someone interested in self defense, might zero at 50 yards or less, while someone looking to do short and long distance range shooting might zero at 100 yards. Seek the advice of a qualified firearms instructor to best understand what zeroing distance is best for you.
