Shooting is the act or process of discharging a projectile from a ranged weapon. The acts of launching/discharging artillery, grenades and guided missiles can be considered acts of shooting; when using a firearm, the act of shooting is called firing as it involves initiating a combustion process. Shooting can take place in a shooting range or in the field, in shooting sports, hunting or in combat; the person involved in the shooting activity is called a shooter. A skilled, accurate shooter is a marksman or sharpshooter, a person's level of shooting proficiency is referred to as their marksmanship. Shooting has inspired competition, in several countries rifle clubs started to form in the 19th century. Soon international shooting events evolved, including shooting at the Summer and Winter Olympics and World Championships; the International Shooting Sport Federation still administers Olympic and non-Olympic rifle, pistol and running target shooting competitions, although there is a large number of national and international shooting sports controlled by unrelated organizations.

Shooting technique differs depending on factors like the type of firearm used. Breathing and position play an important role when handling a rifle; some shooting sports, such as IPSC shooting and biathlon include movement. The prone position, kneeling position, standing position offer different amounts of support for the shooter. In the United Kingdom shooting refers to the activity of hunting game birds such as grouse or pheasants, or small game such as rabbits, with guns. A shooter is sometimes referred to as a "gun". Shooting may refer to the culling of vermin with guns. Clay pigeon shooting is meant to simulate shooting live pigeons released from traps, after doing so was banned in the United Kingdom in 1921. Shooting most refers to the use of a gun, although it can be used to describe discharging of any ranged weapons like a bow, slingshot or blow tube; the term "weapon" does not mean it is used as a combat tool, but as a piece of equipment to help the user best achieve the goal of their activities.

Shooting is used in warfare, self-defense and law enforcement. Duels were sometimes held using guns. Shooting without a target has applications such as celebratory gunfire, 21-gun salute, or firing starting pistols, incapable of releasing bullets. In many countries, there are restrictions on what kind of firearm can be bought and by whom, leading to debate about how effective such measures are and the extent to which they should be applied. For example, attitudes towards guns and shooting in the United States are different from those in the United Kingdom and Australia. Canting is an alignment issue; because scopes need to be mounted to a rifle in perfect parallel to the barrel and to ensure the cross hairs sit where a bullet will go, a small variation of ¼ of one degree can cause great problems at longer ranges. A locking bar holds the mount in a perfect 90 degree to the rail system whereas a non-locking bar system can cant to the left or right; this canting is caused by not matching the clamping surface to the rail.

When tightened down, stress exerted on the base can cause the scope to be off from the POI by as much as several feet at 100–200 yards and gets progressively worse as range increases. Lower grade materials used in manufacturing of scope bases, inconsistent design tolerances from one manufacturer to another and other factors can cause twisting stress and cause the mount to move out of parallel with the rifle barrel; the locking bar system allows for stress to be distributed and prevent canting of the scope mount. Another form of scope canting is caused by the rings themselves; some mounts either have four screws on top of the scope ring that hold the scope in place. With the two-screw style, the ring aligns well but does not have the strength of the four screw system; when tightening the screws of the four screw type, the scope can twist in place, causing misalignment. The four basic "NRA" or "competition" or "field" shooting positions, in order of steadiness/stability, are prone, sitting and standing.

Another common, but aided, shooting position is the bench shooting position. There are numerous shooting aids from monopods to tripods to sandbags and complete gun cradles; the steadiest and by far the easiest to master. Done correctly, it can be as steady as shooting from a bench rest. The least used in the field because, all too vegetation gets in the way and obscures the view. Variations:classic – with the body at an angle modern – with the body more directly behind the rifle with the shooter's strong side leg bent. Test for correct body position: wrap your arm into the hasty sling and drop down into prone, sighting at the target. Close your eyes; when you open them you should still be aiming at the target. If you aren't your position is off. If the shooter's sight picture returns after the firm kicks to each muzzle body alignment is good. If not, adjustment is needed. Usual advice is to use a sling for this position Aided prone position – prone with pack or bipod This position is easy to get into, but more difficult to get out of and provides clearance for low to medium-height obstacles that would interfere with

Cape Falcon Marine Reserve

Cape Falcon Marine Reserve in Oregon, USA, is a protected area located between Manzanita and the unincorporated community of Falcon Cove Beach in Tillamook and Clatsop Counties on the northern coast of Oregon. It is off the shore of Oswald West State Park; the marine reserve is part of Oregon's network of five marine reserves spread down the coastline. Its restrictions went into effect on January 1, 2016. Cape Falcon Marine Reserve is the second largest in Oregon's system with 12.4 square miles of ocean habitats in the marine reserve and an additional 7.6 square miles in two types of marine protected areas. In the marine reserve, no take of any marine resources is allowed; this includes no harvest of no ocean development. However, safe passage and anchoring of boats are allowed as long. In the Cape Falcon Shoreside MPA only fishing from the beach is allowed. In the West MPA, only salmon fishing by troll, crabbing, are allowed. Http://
