A sawed-off break-action shotgun of the type commonly known as a lupara. A sawed-off shotgun (also called a scattergun, sawn-off shotgun, short-barrelled shotgun, shorty, or boom stick) is a type of shotgun with a shorter gun barrel—typically under 18 inches (46 cm)—and often a pistol grip instead of a longer shoulder stock.
Intact vehicle tyres are generally only suitable for higher energy projectiles which will easily penetrate their surface. Handgun bullets and shotgun pellets may ricochet back. Granulated rubber (often from shredded tires) is a convenient capture material from which bullets may be separated by gravity during agitation by subsequent bullet impact.
This technique is necessary when the target will have significantly displaced its position during the time the projectile would take to reach the target, which can become the case over very long distances (e.g. a long sniper shot), due to fast moving targets (e.g. aerial dogfight against an opposing aircraft, or anti-aircraft fire against ...
Before the barrel can release the bullet in a consistent manner, it must grip the bullet in a consistent manner. The part of the barrel between where the bullet exits the cartridge, and engages the rifling, is called the "throat", and the length of the throat is the freebore. In some firearms, the freebore is zero as the act of chambering the ...
The Swing rifle was a design developed by a number of target shooting enthusiasts who came together in 1970 at Bisley. The design's primary instigators were George Swenson and Laurie Ingram. [ 1 ] At the time target rifle competition in the UK was dominated by designs based on military actions such as those of the Lee–Enfield and Mauser 1898 .
In ballistics, the elevation is the angle between the horizontal plane and the axial direction of the barrel of a gun, mortar or heavy artillery.Originally, elevation was a linear measure of how high the gunners had to physically lift the muzzle of a gun up from the gun carriage to compensate for projectile drop and hit targets at a certain distance.
The spread of shots from gun A is much smaller than those for gun B. Also, the MPI of A is off the target area, whereas that of B is on the target area. Figure 2 shows the MPIs of the two guns for five serials fired from each gun on different occasions. All the MPIs of gun B are on the target area, whereas those of gun A are well spread.
While standard rifle barrels taper from breech to muzzle, high precision rifles will often use a barrel with far less taper, called a heavy barrel, sometimes leaving the barrel cylindrical all the way to the muzzle, called a bull barrel. Either technique greatly increases the stiffness of the barrel by enlarging the average diameter, but this ...
