A choke is designed to alter or shape the distribution of the shot as it leaves the firearm. For shooting most game birds and clay pigeons, a desirable pattern is one that is as large as possible while being dense enough to ensure multiple hits on the target, at a particular range. The choke should be tailored to the range and size of the targets.
Often, shooters will choose an improved cylinder choke (one with a tighter pattern) or a skeet choke (one with a wider pattern), but this is a matter of preference. Some gun shops refer to this type of shotgun as a skeet gun. Skeet chokes are designed to produce a 30 inch shot pattern at 21 yards.
With an open choke, the reduction in diameter is minimal, so accuracy does not suffer much; tighter chokes, however, deform the slug enough to impact accuracy significantly, and the impact of the slug on the choke (at velocities around 450 meters per second (1500 feet per second)) could also stretch the barrel with repeated firings.
Front cover – The M16A1 Rifle – Operation and Preventive Maintenance by Will Eisner, issued to American soldiers in the Vietnam War. An inadequately maintained firearm will often accumulate excessive fouling and dirt within the barrel and receiver, which not only can clog up the rifling and decrease the firearm's accuracy and precision, but can also interfere with the proper operation of ...

A yellow flag demonstrates the rifle's bolt is open and the breech is clear. Firearm handling safety poster. Gun safety is the study and practice of managing risk when using, transporting, storing and disposing of firearms, airguns and ammunition in order to avoid injury, illness or death.
Double-barreled shotguns are also inherently more safe, [7] as whether the shotgun is loaded or can be fired can be ascertained by anyone present if the action is broken open, for instance on a skeet, trap or hunting clays course when another shooter is firing; if the action is open, the gun cannot fire. Similarly, doubles are more easily ...
A skeet shooter shooting at close targets might use 127 micrometres (0.005 inches) of constriction to produce a 76 cm (30 in) diameter pattern at a distance of 19 m (21 yd). A trap shooter shooting at distant targets might use 762 micrometres (0.030 inches) of constriction to produce a 76 cm (30 in) diameter pattern at 37 m (40 yd). Special ...
