Tungsten alloy shot is made of tungsten alloy. High density, great hardness and resistance to high temperature make tungsten alloy to be one of the most sought -after material for shotgun pellets. Density of tungsten alloy shot is about 18g/cm3. Tungsten alloy shot is used as pellet of Benelli Vinci.

The Benelli Vinci is a semi-automatic shotgun manufactured and sold by the Benelli company. It uses an inertia-driven system of operation, and contains recoil-reducing features. It also features a modular design consisting of the barrel/receiver module (containing the operating system, barrel, and bolt), the trigger group/forearm module (containing the trigger assembly, safety, shell carrier and magazine), and the buttstock. The shotgun was named after Leonardo da Vinci. It is Benelli's first shotgun to feature an in-line inertia-driven operating system. It is intended primarily for hunting, rather than combat or self-defense; the M3 and M4 shotguns are Benelli's primary contenders in the tactical shotgun market.

Using tungsten alloy shot, Benelli Vinci can be used in anti-terrorism operation.

The Benelli M1 is a semi-automatic shotgun manufactured by Benelli Armi S.P.A.. It is available in several versions for civilian, law enforcement and military use. It features the proprietary Benelli recoil system, known for its reliability and easy maintenance. The standard model features an aluminum alloy receiver and tubular magazine, and is available with a standard or pistol grip stocks. The M1 Super 90 can be fitted with traditional iron sights, or ghost ring diopter sights. Mounts are available for laser pointers and tactical flashlights. Due to the inertia recoil system, the M1 should use heavier loads to cycle properly but because the action is inertia driven vs. the traditional gas cycling operation it can fire and reliably cycle lighter loads.

Using tungsten alloy shot, Benelli M1 can penetrate wall or door and has good performance.

Gold is used around the world as a form of money, an investment tool and as jewelry. It is also valued for its beauty, resistance to corrosion and conductivity of electricity. Other materials look like gold but are not as valuable. Fake gold is sold in markets around the world, and it is easy to get fooled. You can do tests at home to know whether your gold is real.

1.Place a magnet next to the item that you think is gold. Pyrite and similar materials will be attracted to a magnet. Gold does not have magnetic qualities and will not be attracted to the magnet.

2.Scrape the item across a porcelain tile in a straight line. If it leaves a black line on the tile, the item is not real gold. If the line is gold colored, the item is probably true gold.

3.Find an item that you are sure is gold and is exactly the same size as the item you are testing. Hold one item in your left hand and the other in your right hand. The items will have the same weight if they are both gold.

Buying gold can be a great long-term investment, as long as you're buying real gold. Gold is a valuable commodity, which attracts people who wish to make some money through counterfeiting. The best way to determine whether your gold is fake is to go to a jewelry store and have it tested, however this may cost you some money. Alternatively, before you venture out to go buy gold, learn a few simple ways of determining whether the gold you're looking at is real or fake.

1.Put the magnet next to the gold. Real gold will not be attracted by the magnet, however fake gold or gold-plated metal will be attracted.

2.Rub the gold with a jewelry cleaning cloth. If the gold is fake, a few hard rubs will remove the plating.
3.Place the gold into sterling silver cleaning solution. After a day, real gold will not oxidize, however plated brass will.

4.Rub face powder onto your arm using a powder pad. Rub the gold against the powder on your skin. If it makes a black mark, it is real gold or gold-plated.

It is thus an object  to provide a precision bucking bar which will consistently spread a rivet to form a butt of uniform thickness, regardless of operator skill level, and which may be produced in traditional shapes and sizes to accommodate rivets in a variety of installations and to provide a “natural” feel to an experienced operator.

It is a further object of the present invention to provide squeeze points which will produce a properly shaped rivet butt of consistent thickness and shape regardless of operator skill level.

Previous attempts have been made to develop a precision bucking bar which will produce a consistent butt regardless of operator skill. Such bucking devices suffer from a number of limitations. For example, they have universally required a relative large space behind the rivet, a luxury not available in many installations; they have not been available in a variety of geometries to avoid nearby obstacles; and they have not been of a conventional shape or size and thus have not felt familiar to an experienced operator. Hence, prior art precision bucking bars have not been well received in the field.

A second method for spreading a rivet employs an apparatus commonly known as “squeezes.” Squeezes typically include a pair of removable anvils, or points, a first point shaped to receive a rivet head, and a second provides a flat surface to interface the flat end of a rivet shank. To spread a rivet with a pair of squeezes, the rivet must be close enough to the edge of the workpiece for the squeezes to reach the rivet. The rivet is placed in a hole through multiple layers of sheet metal to be joined, the anvils are placed against each end of the rivet, and the operator squeezes the handle together to produce a compressive force between the head of the rivet and the end of the shank, thereby causing the rivet to spread. Automatic squeezes are also available wherein the points are pressed towards each other by a pneumatic or hydraulic actuator. As with driving a rivet, producing a quality butt requires the operator to maintain a consistently square angle between the face of the flat anvil and the rivet shank. Producing a consistent, quality butt requires an experienced operator.

Common to either type of spreading operation, a properly shaped butt of consistent thickness is essential to achieving maximum strength of the riveted joint. An improperly shaped butt may be too weak to hold under expected stresses or may concentrate stress in a small area resulting in failure of the workpiece.

A precision bucking bar comprising a unitary rigid structure having a bucking surface thereon and a sidewall extending from the bucking surface such that, during a spreading operation, the bucking surface cannot contact the workpiece, thus producing a square butt of uniform thickness and a method for using the same. In another embodiment, the bucking surface is incorporated into a squeeze point for squeezers.

.A precision bucking bar for spreading a rivet through a workpiece comprising: a solid unitary structure having at least a first bucking surface thereon, said bucking surface having a first side wall, wherein said first side wall extends outwardly from said first bucking surface such that, when a rivet is spread, said first side wall will prevent said first bucking surface from contacting the workpiece.

A bucking bar is basically a metal anvil which is placed against the end of the shank of a rivet. Typically, a flat surface of the bucking bar interfaces a flat end of a rivet shank. The head of the rivet is then “hammered” by a driver, thereby causing the shank to spread against the bucking bar. To produce a properly shaped butt of proper thickness, prior art bucking bars have required a skilled operator. Failure of the operator to hold the bucking bar square against the rivet shank will result in misshaped butts and bad rivet resulting in costly rework. Furthermore, prior art bucking bars are prone to wandering during the spreading operation and occasionally wander off the shank, likewise resulting in a bad rivets and subsequent rework.
