When zeroed for 100 yards (91 m), the arc-trajectory of the standard high-velocity .22 LR with a 40 gr (2.6 g) bullet has a 2.7-inch (69 mm) rise at 50 yards (46 m), and a 10.8-inch (27 cm) drop at 150 yards (140 m). [12] A .22 LR rifle needs to be zeroed for 75 yards (69 m) to avoid overshooting small animals like squirrels at intermediate ...

Generally some may claim that for the .22 LR cartridge any distances over 100 metres (110 yd) is considered long range. For centerfire intermediate rifle calibers, some might say that everything over 300 to 400 metres (330 to 440 yd) is considered long range, while some may claim that long range "starts" at 500 metres (550 yd).
Groups for rifles are traditionally shot at either 100 meters or 100 yards (91 m). At 100 yd a minute of arc equals 1.047 inches (26.6 mm), and the one MOA group (approximately 1/3 or 0.3 mil) is a traditional benchmark of accuracy. Handguns are generally used at closer ranges, and are tested for accuracy at their intended range of use.
For shorter ranges (less than about 100 yards (91 meters)) rimfire cartridges such as .22 Magnum and .17 Hornady Magnum Rimfire are popular. The .22 Long Rifle will also do, but the low muzzle velocities result in a supersonic to subsonic transition on the way to the target, which can negatively affect accuracy.

It was established to address the fact that most localities do not have access to 1000 yard ranges, but nearly all localities have 100-yard ranges and most shooters own .22 rifles.
