Pellet Chips Metal Balls: Pallets, in general, pellets have a shape known as diabolo which means that the front and rear sections are of larger diameter than the middle. One reason for this is to reduce the friction that would result if more of the pellet made contact with the barrel. Even though some air guns are rather powerful, the amount of work necessary to push the pellet down the barrel would be large if the pellet had a shape like a bullet.
Another feature of pellets is that they have hollow bases (the skirt area of the pellet) that are generally larger in diameter than the front section (known as the head of the pellet). This enables the skirt to effectively seal the bore against the pressure pushing on the base of the pellet while the friction on the head area is not too high.
The pellet velocity from any air rifle depends on the weight of the pellet. Heavier pellets simply cannot be driven as fast as lighter ones. However, heavier pellets normally retain their velocity better as a result of their having higher ballistic coefficients. Even though initial velocity is lower, a greater percentage of that velocity is retained down range. Although a great deal of emphasis is placed on high muzzle velocity, pests are normally shot at some distance from the muzzle so the ability of the pellet to retain velocity is also important.

Pelletizing is the process of compressing or molding a material into the shape of a pellet. By extruding the material through a screen, the pellets are formed by shaving off the parts in predetermined lengths just before hardening. A wide range of different materials are pelletized including metals and chemicals. Ninety percent of pellets are usually made from rod varying in different diameters depending upon the requirement of the user. Uniformity in shape is an attribute of pellets.
Metal chips are generally irregular shaped portions of metal fragments where the key to selection is the “available surface area.” Chips come in a variety of sizes and shapes which can range from being quite large (an inch or two in diameter to fractions of inches). Generally, the smaller the chips, the more surface area there is of the material being used.
Chips are often made by “shaving” metals with burring type bits. The size of the chips depends upon different criteria such as, the size and roughness of the bit as well as the hardness of the material being shaved or chipped off. Selection and use of chips, like pieces, are often determined by the amount of surface area available on the material.
Metal balls are rolling, spherical elements that exhibit greater strength and toughness than plastic and ceramic balls. They have a sufficient hardness for many industrial ball applications, and most products are electrically conductive. Some steel, nickel, and cobalt balls can be magnetized. Metal balls made from certain alloys can also provide corrosion resistance and refractory resistance.
