What is the Power Factor in Shooting?
Power factor is a critical metric used in competitive shooting to measure the potential energy and effectiveness of ammunition. It's calculated by multiplying the bullet weight (in grains) by its velocity (in feet per second) and then dividing by 1000. This formula provides a standardized way to classify ammunition across different calibers and shooting disciplines.

Power factor is a calculation in competitive shooting that multiplies bullet weight by velocity and divides by 1000. It helps classify ammunition and determine scoring in shooting competitions. The formula allows for a standardized way to compare different types of ammunition across various calibers.
Q: How do I calculate the power formula calculator factor?
Calculate the power factor by multiplying the bullet weight (in grains) by its velocity (in feet per second), then dividing by 1000. For example, a 180-grain bullet traveling at 1000 fps would have a power factor of 180. You can use our calculator above to easily compute this for different ammunition types.
Q: Why is the power formula calculator factor important in shooting competitions?
Power factor determines scoring advantages, and division classifications, and ensures a level playing field by standardizing ammunition performance across different calibers and weapon types. Different competitions have varying power factor requirements that can affect your scoring and division placement.
Q: What's the difference between major and minor power formula calculator factors?
Major power factor typically provides higher scoring values for hits, while minor power factor results in lower scoring. The specific thresholds vary by competition organization, such as USPSA and IPSC. For example, in USPSA, the major power factor for handguns is 165, while the minor is 125.
Q: Do all shooting competitions use a power factor?
Not all competitions use the power formula calculator factor, but it's common in practical shooting sports like USPSA, IPSC, IDPA, ICORE, and SASS. Each organization has its specific requirements and calculations. Some competitions may have different rules or use alternative methods of classifying ammunition.
