Q:Information: - A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves ("rifling") cut into the barrel walls. The raised areas of the rifling are called "lands," which make contact with the projectile (for small arms usage, called a bullet), imparting spin around an axis corresponding to the orientation of the weapon. When the projectile leaves the barrel, this spin lends gyroscopic stability to the projectile and prevents tumbling, in the same way that a properly thrown American football or rugby ball behaves. This allows the use of aerodynamically-efficient bullets (as opposed to the spherical balls used in muskets) and thus improves range and accuracy. The word "rifle" originally referred to the grooving, and a rifle was called a "rifled gun." Rifles are used in warfare, hunting and shooting sports. - A shooting sport is a competitive sport involving tests of proficiency (accuracy and speed) using various types of guns, such as firearms and airguns. Shooting sports are categorized by the type of firearm, target, and distance at which the targets are shot. - A silver medal in sports and other similar areas involving competition is a medal made of, or plated with, silver awarded to the second-place finisher, or runner-up, of contests or competitions such as the Olympic Games, Commonwealth Games, etc. The outright winner receives a gold medal and the third place a bronze medal. More generally, silver is traditionally a metal sometimes used for all types of high-quality medals, including artistic ones. - The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm. The term is from Middle French and originated as the diminutive of the word boulle (boullet) which means "small ball." Bullets are made of a variety of materials. They are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a large numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, and warfare. - Hunting is the practice of killing or trapping animals, or pursuing or tracking them with the intent of doing so. Hunting wildlife or feral animals is most commonly done by humans for food, recreation, to remove predators that are dangerous to humans or domestic animals, or for trade. Lawful hunting is distinguished from poaching, which is the illegal killing, trapping or capture of the hunted species. The species that are hunted are referred to as game or prey and are usually mammals and birds. - Emil Kellenberger ( 3 April 1864 - 20 November 1943 ) was a Swiss sports shooter who competed in the early 20th century in rifle shooting .

Its mission is enshrined in the Olympic Charter: to support the development of competitive sport by ethical and environmentally sustainable means. - At the 1900 Summer Olympics, 9 shooting events were included.

The offense, the team with control of the oval-shaped football, attempts to advance down the field by running with or passing the ball, while the team without control of the ball, the defense, aims to stop their advance and take control of the ball for themselves. The offense must advance at least ten yards in four downs, or plays, or else they turn over the football to the opposing team; if they succeed, they are given a new set of four downs. Points are primarily scored by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins.
