Range for the use of Pepperballs for self defense or home defense vary, but Pepperball states that their LifeLite is capable of firing .68 caliber Pepperballs approximately 60 feet or roughly 20 yards. Other pepperball-firing options, including the Umarex HDP pistol, fires smaller .50 caliber Pepper balls so range and impact energy may be somewhat reduced, but not drastically.
As all Pepperball – firing airguns are powered by CO2 cartridges, velocity, range and impact energy will vary with temperature fluctuations, the amount of CO2 remaining in the cartridge loaded into the airgun and how fast the shooter fires. Baseline performance is generally measured at room temperature.
