Hey Nut, I've seen it advertised as having a range of appx 20 meters, but I can sit on my front porch and send the neighbors dog home and keep his attention across my yard, across the highway and into his own yard if I shoot it like an artillery piece. After about 30 yards it starts a curve and you have to "walk" the rounds in, but you can see them and it's a lot of fun without harming the neighbors dog. At 20 feet and under, it packs a good bit of punch. My first mouse was just "dazed" and I tossed him outside, the second was a good clean kill, blood and everything! I kinda miss the little buggers sneeking around for target practice.
