Alright, my father owns a landscaping company and one of his clients is a location that does weddings/receptions, banquets, parties, etc.
There is a creek that runs through the back of it and he is having awful problems with armadillos digging up and eating the roots/bulbs of plants. He's tried live traps and catches racoons, poison with no result, and has now called me asking to set out with a pellet gun (it's in the in city) to pop the little boogers off. I looked it up, and shooting a pellet gun in this particular city is a noise violation (hence the need for quiet) but no other offense.
I haven't shot pellet guns with the intent of killing things since i kid, picking squirrels off with my pump daisy. I'm trying to stay moderately low on price (under $100), but get something that can handle the hide on those buggers and get good enough penetration to kill 'em.
