Lead is also involved in the primer (lead
styphnate) to start the combustion of the gun powder, which propels the bullet down the barrel.
(6) Another example is lead nitrate (used in lead
styphnate) which is used in almost every gun primer for small and medium caliber ammunition.
By 1979 chemists were working on a dry powder mixture for filling .22 cases that was non-explosive until exposed to water, whereupon a chemical reaction converted it to conventional lead
styphnate (primer compound).
Primer mixtures often contain three inorganic compounds: lead
styphnate (initiator), antimony sulfide (fuel), and barium nitrate (oxidizer) (Wolten et al.
The primer itself is the basic lead
styphnate that has low pressure but a high heat yield.
plant (with CCI primers because Federal can't make MIL-SPEC lead
styphnate and FA956 mix) then shipped the cartridges to LCAAP (bulk packed) to be linked with LC Tracer and packed out for delivery.
Soon the T53 was replaced with the modern non-corrosive lead
styphnate mix and designated FA 36 in 1958.
Most primers used in North America consist of lead
styphnate (Pb) as an initiating explosive, barium nitrate (Ba) as an oxidizer, and antimony sulfide (Sb) as a fuel; therefore, a combination of these elements in a single particle proves very significant.
"The primary ignition component is still based on lead
styphnate, which is the standard primary explosive used in small arms primers, though Federal's formula is unique.
Liverpool Crown Court heard that Mrs Wilkins was working with lead
styphnate, a sensitive primary explosive, in 2005 when she was killed.
Liverpool Crown Court heard that Mrs Wilkins was working with lead
styphnate, a sensitive primary explosive, on March 2, 2005 when she was killed.Investigators found that the company allowed unsafe working procedures to develop by providing too little supervision and monitoring.
