Thanks for the info. The reason for asking was I am closer than 500 feet to my neighbors' houses and I have a problem with the invasive species English Sparrows threatening my bluebirds trying to nest in my nesting boxes. I was hoping there was a better solution to hit a sitting sparrow at a typical range of 25 feet besides a handheld slingshot. My accuracy with the slingshot is terrible, I was hoping for some low velocity short range implement that would be accurate enough at short ranges to do the job.
