Varmint hunting is the practice of hunting vermin, generally small mammals targeted as a means of pest control, rather than for food. Varminter may refer to a varmint hunter, or describe hunting equipment either specifically designed for, or suitable for varmint hunting, such as a varmint rifle. Varmint hunters may hunt to exterminate a nuisance animal from their own property, to collect a bounty offered by another landowner or the government, or for amusement.
The term varmint is a US colloquial term for vermin, though it refers more specifically to mammal or bird pests, including:
predators which can kill farm animals: badger, bald eagle, barred owl, bobcat, cooper's hawk, cougar, coyote, feral dogs, goshawk, foxes, golden eagle, great horned owl, lynx, mink, osprey, raccoons, screech owl, snakes, snapping turtles, snowy owl, sparrowhawk, weasel, wolverine, and wolves
rodents and lagomorphs that can damage cropland or pastures or carry disease: beaver, groundhogs, muskrat, prairie dogs, porcupine, rabbits, rats, and squirrels
birds perceived as damaging to crops: crows and raven, as well passenger pigeons and Carolina parakeets, both of which were driven to extinction in part by pressure from indiscriminate hunting
invasive species, such as starlings, that are displacing desirable native species
Since varmint hunting is a form of pest control, and minimally regulated by law, the definition of what constitutes a varminter model tends to vary by regional pests. The definitive varmints are ground burrowing animals such as groundhogs and prairie dogs. These animals are small and difficult to approach closely, and hunting them requires a long range, highly accurate rifle. Because of this, models labeled Varminter will generally fit the following characteristics:
high velocity, for a flat trajectory (see external ballistics)
lightweight bullets, designed for minimum penetration (see terminal ballistics)
extreme accuracy, for the ability to hit small targets at long range (see accurize)
