The Definition of Model 70 Type Safety
Model 70 Type Safety
A small lever mounted to the cocking piece of a Winchester Model 70 rifle, rotating on a vertical axis from front (Fire),
halfway back (Safe, but allowing bolt movement), and fully back (Bolt and firing pin locked Safe).
While, like the Mauser, commendable for locking the firing pin instead of just the trigger,
its fore and aft movement is both easier to operate and it allows lower mounting of telescopic sights,
reducing parallax between the line of sight and the line of the bore and increasing the range of
distances for which the scope may be reliably sighted-in.

A shotgun term which refers to the manner in which the pellets spread out as they exit the gun.
"The pattern" refers to the overall shape of the entire set. A tight pattern is one in which the pellets are closely grouped when they land on target.
A loose pattern is one in which the pellets are widely spread.
A popular but imprecise term used to refer to the ability of a small arms cartridge to cause a human assailant or an animal to be immediately incapacitated when shot with it. A more precise term is be Wound Trauma Incapacitation (WTI).
The use of an electric current to fire a cartridge, instead of a percussion cap. In an electronic-fired firearm an electric current
is used instead to ignite the propellant, which fires the cartridge as soon as the trigger is pulled.
A concave, semi-cylindrical surface cut into the forward lump of a barrel set of a break-open firearm which revolves about the hinge-pin when the gun is opened.
A mechanical device that protrudes from the gun when a round is in position ready to be fired, giving a visual and tactile indication that the gun is loaded.
Two independent rifles, built on one frame, designed to allow two virtually instantaneously quick, totally reliable shots.
The barrels may be arranged either side-by-side or over-and-under. The apogee of the gunmaker's art.
Particularly useful against dangerous game, which may be moving, and in your direction, with vengeance on its mind.
Smith & Wesson term for a revolver grip design introduced in the 1930s where the top of the grip extends higher than it had in earlier configurations, to provide a more comfortable hold.
An artillery piece used to fire shells over short ranges at very high trajectories.
Also called black powder, gunpowder is a mixture of sulfur, charcoal, and potassium nitrate. It burns rapidly,
producing a volume of hot gas made up of carbon dioxide, water, and nitrogen, and a solid residue of potassium sulfide.
Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant
in firearms and as a pyrotechnic composition in fireworks. The term gunpowder also refers broadly to any propellant powder.
Modern firearms do not use the traditional gunpowder (black powder) described here, but instead use smokeless powder.
Hearing protection that fits inside the ear canal.
A metal plate on which the firing mechanism is mounted on percussion and earlier firearms.
An oversized, lightweight housing that allows a sub-calibre projectile to be fired in a larger-diameter bore, usually in the interest of increased velocity.
The sabot falls away from the actual projectile upon exiting the muzzle.
For example, a hunter could use his .30-30 deer rifle to shoot small game with .22 centerfire bullets.
A larger class of machine gun..
A firearm that can be separated into (at least) two subassemblies in order to make a shorter package than when put together, without tools.

Sometimes spelled Bi-Pod.
A support device that is similar to a tripod or monopod, but with two legs. On firearms, bipods are commonly used on rifles to provide a forward rest and reduce motion.
The bipod permits the operator to rest the weapon on the ground, a low wall, or other object, reducing operator fatigue and permitting increased accuracy.
For self-defensive shooters, Center Of Mass (COM) represents the area of an attackers torso within which the most vital organs are likely to be disrupted by a gunshot.

To jerk a firearm off target inadvertently in the instant of firing in timid anticipation of recoil. Commonly caused by learning to shoot with a gun more powerful then they are ready for.
The spotter is a helper who gives the shooter guidance on how to hit a particular target.
In some cases the spotter may just report the location of the bullet impact. In other cases they may judge the speed and direction of
the wind, determine the range, and give the shooter the settings to be used on the sights.
