Streukreisgröße

Streukreisgröße refers to the diameter of the smallest circle into which all bullet holes can be contained at a given shooting distance. It is a common metric used to evaluate the accuracy of firearms and ammunition. A smaller Streukreisgröße indicates a more precise combination of gun and bullet. This measurement is typically taken under controlled conditions, often at a standardized distance like 100 meters or yards.

To determine Streukreisgröße, a shooter fires a specific number of shots, usually five or ten, at a target. The size of the resulting cluster of bullet holes is then measured. Specialized tools or software are employed for precise measurement, ensuring consistency. Factors influencing Streukreisgröße include the firearm's mechanical precision, barrel quality, the ammunition's consistency in terms of bullet weight and propellant charge, and the shooter's skill.

Different shooting disciplines and firearm types have varying expectations for acceptable Streukreisgröße. For competitive shooting, very small groups are essential. For hunting, a certain level of precision is required to ensure a humane kill. When comparing firearms or ammunition, Streukreisgröße is a key performance indicator. It is important to note that environmental factors like wind and temperature can also affect the actual dispersion of shots, even with a highly accurate firearm and ammunition. Therefore, reported Streukreisgrößen are often averages derived from multiple shooting sessions to account for these variables.
