Ruger No. 1 Varmint rifle in .223 Remington. Note the heavy barrel, bipod rest, large telescopic sight, and "dope" sheet on the stock for windage

A varmint rifle is a small-caliber precision firearm or high-powered airgun primarily used for both varmint hunting (the elimination of outdoor animals which harass properties) and pest control (the eradication of indoor infestation by destructive species). These tasks include killing three types of pests or nuisance animals that spread diseases or destroy crops or livestock:

Varmint guns fill a design gap between the more powerful big game rifles and the less powerful rimfire firearms. Big game rifles are more suitable for stalking and taking down individual large-sized animals such as reindeer, elk and buffalo at medium ranges, but not adequate for frequent repeated firing. Rimfire firearms (such as the highly popular .22 LR caliber) are best used to shoot small vermin such as squirrels and rats at close distances, and are somewhat underpowered for many outdoor rodents (which are often alert enough to spot hunters from a long distance away and flee or hide underground), small predators such as coyotes and larger feral animals such as goats and pigs. The varmint rifles are very suitable for repeated medium/long-range shots from a fixed firing position, thus fulfilling and overlapping the functional demands with both in terms of hunting applications.

Common design elements

While any rifle of sufficient power can be used to dispatch targets of opportunity (the venerable .30-30 Winchester lever action and the Ruger Mini-14 are common truck guns or ranch guns kept handy for this) the deliberate taking of varmints requires special characteristics more common to target rifles than "normal" hunting rifles.

General characteristics

"DOPE sheets" for calculating bullet drop and wind drift are frequently used

Varmint rifles can typically be distinguished from other light-caliber hunting or plinking rifles in the use of heavier barrels and (often) omission of open sights. Use of magnifying optics allows for more accurate fire (often on very small, distant targets). Barrels will generally be free-floated, and other accurizing techniques will be performed, either by the manufacturer or the owner. The stocks will generally have wider forends, designed for use on stable sandbag rests, and high combs for easy use with optics.

Since part of the definition of a "varmint" is that it is a nuisance, varmints are not stalked, but rather they are hunted from a fixed position. This makes weight of little consideration in a varmint rifle, so heavy barrels are common. Varmints are also not subject to the same bag limits as game animals are, so far more shots may be fired. The heavier barrel is, in general, more accurate than a light barrel, plus the extra mass helps reduce the felt recoil and absorb the heat from more shots before expanding and potentially reducing accuracy. Folding shooting benches and sandbag rests help provide a stable base for the shooter, allowing the maximum accuracy to be extracted from the rifle.


An alert rodent will usually hide underground before hunters can approach within 100 metres (110 yd).

Since varmints are generally smaller animals, large, heavy bullets are not needed. A light, fast bullet gives a flat trajectory, making range estimation less vital for accurate shot placement. Velocities for modern varmint rounds are usually in excess of 3,000 ft/s (910 m/s) such as the .223 Remington and some like the .220 Swift can exceed 4,000 ft/s (1,200 m/s). This allows long range shots with a short time of flight, and little change in trajectory at different ranges (see external ballistics). A bullet drop of only a couple of inches (about 5 cm) is enough to cause a miss on smaller varmint animals; so flat trajectories increase hit probability at long ranges. Fast, lightly constructed bullets have additional advantages of rapidly disintegrating upon initial contact. Disintegration minimizes the range of ricochet particles; and energy release of disintegration kills small animals more quickly than a penetrating wound.[2]

Rifles firing .22 caliber bullets became popular varmint guns after World War I. Calibers up to .264 caliber (6.5 mm), including .243 Winchester, 6mm Remington and .25-06 Remington, became popular for ranges over 200 metres (220 yards) as the ballistic advantages of heavier bullets were recognized.[3] Varmint shooting is one of the few areas where calibers smaller than .22 (5.56 mm) are found; the .17 Remington and various other .17 caliber (4.5 mm) wildcats have a vocal following, and the new .204 Ruger is well suited to varminting, and may be the first in a new line of .20 caliber (5mm) rounds.

For shorter ranges (less than about 100 yards (91 meters)) rimfire cartridges such as .22 Magnum and .17 Hornady Magnum Rimfire are popular. The .22 Long Rifle will also do, but the low muzzle velocities result in a supersonic to subsonic transition on the way to the target, which can negatively affect accuracy.

Varmint cartridges

Typical varmint rifle cartridges on a 0.25-inch (6 mm) grid (from left to right): .22 long rifle for very small animals at ranges less than 100 meters, .22-250 represents the high velocity .22 calibers for longer range shooting, and .25-06 for larger animals at ranges up to 400 meters.

Action types

Bolt-action rifles dominate the class, with a few specialized AR-15 variants (often referred to as "modern sporting rifles") and single-shot rifles making up the rest. Most bolt-action rifles, if accurized, can be successfully used for varmint hunting. While nearly all varmint guns are rifles, there are a few pistols, generally single shot and bolt-action pistols in rifle calibers such as those developed for metallic silhouette shooting, that have sufficient accuracy, range, and trajectory to allow them to be used for varmint shooting. The Remington XP-100 bolt-action pistol and its aptly named .221 Fireball cartridge, introduced in 1963, were developed for varmint hunting; the full name is the "Model XP-100 Varmint Special".

For varmint and pest control in urban areas, air guns make suitable choices. While the limited power of an air rifle (generally far less than a .22 Long Rifle) limits its usefulness to small rodents at very short range, the limited penetration and low noise allows them to be used in areas where use of firearms is impractical. The popular air gun sport of field target is based on small game and varmint shooting, with targets often shaped like rabbits, squirrels, and other suitable small varmints. The low velocities of air gun pellets makes accurate range estimation paramount, so high magnification telescopic sights are used, with calibrated focus knobs that serve to estimate the range.
