Small arms ammunition will be available in its present form for the foreseeable future. Its function will continue to be to propel a projectile over a distance to strike a target. Variations in the material and design of this ammunition will be in response to the specific needs of the many groups of small arms users.
The military will continue to develop ammunition which can penetrate and incapacitate a wide variety of targets ranging from humans to sophisticated electronic equipment. Currently, they are investigating "non-lethal" weapons and ammunition which will incapacitate a target without destroying it. Small arms weapons in this category include hand-held chemical lasers to knock out electronic sensors, and foam guns which shoot a sticky foam that envelops the target. These non-lethal devices would supplement, not replace, the conventional small arms weapons and ammunition.
Police are also interested in non-lethal weapons and ammunition. Rubber bullets that impact without penetration are already in use for riot control. Another device is a shotgun which fires a small bean bag. When fired at a close range, the bean bag hits with the impact of a punch to momentarily incapacitate the target.
Hunters will want ammunition which hits accurately and kills with a single shot. Much of the development of commercial small arms ammunition has been in this area, and has included many variations in powder loads and bullet configuration.
Target shooters will continue to develop ammunition which offers excellent accuracy and repeatability for competition shooting.
Tungsten alloy is widely used in military field, It is one of the raw materials of ammunition. It has many special properties. It has high density and high melting point ,which is fit for military use.Compared to other materials, Tungsten alloy is non-toxic and environmental friendly. With high temperature resistance and low vapor pressure, it is also used in other field.
