Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim. An ideal group would be one where all shots land in a hole no larger than the diameter of a single bullet; this would indicate zero dispersion. The most common way of measuring groups then is to measure the edge to edge distance of the farthest holes, and subtract the bullet diameter, which gives the ''center to center'' or ''c-c'' measurement of the group. This can be expressed in linear measures (''a 30 mm group at 100 m'', or ''a one inch group at 100 yards'') or in angular measures (''a [[milliradian]]'' or ''[[Minute of arc#Firearms|MOA]] group''). Groups for rifles are traditionally shot at either 100 meters or {{convert|100|yd}}. At 100&nbsp;yd a minute of arc equals {{convert|1.047|in}}, and the one MOA group (approximately 1/3 or 0.3 mil) is a traditional [[Benchmarking|benchmark]] of accuracy. Handguns are generally used at closer ranges, and are tested for accuracy at their intended range of use. Also of importance is the number of shots fired. Statistical likelihood says the fewer shots that are fired, the smaller the dispersion will be.<ref name=groupsize>{{cite web|url=http://www.snipercountry.com/compendium/Comp_G.htm |title=G |accessdate=2007-09-06 |archiveurl=https://web.archive.org/web/20071006141201/http://www.snipercountry.com/compendium/Comp_G.htm |archivedate=6 October 2007 |url-status=dead }}</ref> 3 or 5-shot groups are acceptable for zeroing the sights and rough accuracy estimates, but most shooters{{who|date=August 2018}} consider 10-shot groups to be the minimum for accuracy comparisons.
