Smith Wesson

As of late 2004 the situation with regard to negligent marketing claims remains mixed. More than two dozen cities have filed suits against gun manufacturers or distributors on this or other grounds about half of the suits were dismissed before trial. In March 2000 Smith Wesson (a major... 

December Smith Wesson enters into a legal setdement with the city of Boston. It resolves some of the issues in the earlier failed agreement, and is restricted only to Smith Wesson s products. However, a number of gun advocacy groups organize a boycott of Smith Wesson to protest what they view as caving in to antigun forces.

Centerfire cartridges were produced by Pauly in 1808 but it was not until 1854 that the firm of Smith Wesson perfected and patented both the centerfire and rimfire metallic cartridge case. Since this time cartridge development has consisted of many small improvements, some resulting from advances in... 

The first serious attempt to solve the problem at source was in 1978 when Smith Wesson encased the entire lead bullet in a coating of black nylon (Nyclad ammunition). This substantially reduced the amount of lead released into the atmosphere from the discharge process, greater than 60% reduction when compared to the cleanest of conventional lead bulleted ammunition. As mentioned previously, most of the lead originates from the bullet, the lead in the primer making a much smaller contribution. 

Analysis of a round of. 38 Special caliber, Smith Wesson Nyclad ammunition revealed that the cartridge case and primer cup are nickel-plated brass, no inorganic additives to the propellant were detected, the primer composition contains lead, antimony, and barium, the bullet core is antimony-hardened lead, and the bullet jacket contains traces of calcium, cobalt, titanium, and phosphorus. 

The nylon-coated bullets from Smith Wesson and the Geco TMJ bul-let/new primer composition, although effective in markedly reducing the lead levels, did not totally eliminate the problem. In 1983, Dynamit Nobel introduced 9 mmP caliber ammunition with a TMJ bullet and a primer free of lead, antimony, barium. The new primer type was called Sintox. A typical Sintox primer composition contains 15% diazodinitrophenol (DDNP) and 3% tetracene as the explosive ingredients, 50% zinc peroxide as the oxidizer, 5% of 40-pm size titanium metal powder, and 27% nitrocellulose as propellant powder.202 As expected, other munitions manufacturers eventually introduced similar ammunition, some with primers that were lead free but containing antimony and barium and others free of lead, antimony, and barium. The objective was to produce ammunition which performed satisfactorily in every way and did not produce any toxic product on discharge.
